stationary ball B. Ball A bounces back; B moves
off slowly to the right. Which has the greater
mass, A or B?​

Jim and Bob send a car careening off a cliff. The car has a velocity of 16 m/s when it went off the cliff and it lands 35 m from the base of the cliff. How long was the car in the air? How high is the cliff?

Answers

Answer:

The time spent in air by the car is 2.19 s

The height of the cliff is 58.5 m

Explanation:

Given;

initial velocity of the car, u = 16 m/s

horizontal distance traveled, R = 35 m

The horizontal distance or range of a projectile is given as;

R = vt

where;

t is the time spent in air by the projectile

t = R/v

t = 35 / 16

t = 2.19 s

The height of the cliff is given as;

h = ut + ¹/₂gt²

h = (16 x 2.19) + ¹/₂(9.8)(2.19)²

h = 58.5 m

Diana hangs a lead cylinder with a force of 12 N from a model bridge.


Which vector(s) accurately illustrates the reaction force of the bridge on the lead cylinder?

Answers

The answer would be A and I’m pretty sure of thta

The action and reaction law allows us to find that the reaction force, the weight of the cylinder, is:

  12 N force directed upward

Newton's third law or action and reaction law, establishes that if two bodies interact with each other the force that one applies to the other, is equal in magnitude to the force of the second on the first but in the opposite direction, that is, all forces act in pairs one in each body that interact.

Forces with these characteristics are called action and reaction.

In this case we have a hanging cylinder, with the cylinder it has mass so the weight is 12 N it acts on the table in a downward direction, let's say this is the action force.

In response to this force, the table exerts a force on the cylinder of equal magnitude but in the opposite direction, which is why it is directed upwards.

let's analyze the force diagram

When analyzing the forces shown in the diagram, the forces of equal magnitude to the weight are the first two

The weight is directed downward, the answer must be directed upward.

In conclusion using theaction and reaction law we find that the answer for reaction force is:

    12 N force directed upward

A dog pulls on a leash with a force of 15 23 is a big dog. The leash makes an angle of 36.7 degrees to the horizontal. What are the x

and y components of the force?

Answers

Answer:

[tex]x = 12.027N[/tex] and [tex]y = 8.964N[/tex]

Explanation:

The first sentence of this question is not explanatory enough. However, I'll assume the force to be 15N

[tex]Force = 15N[/tex]

[tex]\theta = 36.7[/tex] to the horizontal

Required

Solve for the x and y components

Since the given angle is to the horizontal, the x and y coordinates are calculated using the following illustrations.

[tex]Sin\theta = \frac{y}{Force}[/tex] ---- y component

[tex]Cos\theta = \frac{x}{Force}[/tex] ---- x component

Calculating the y component.

Substitute 15 for Force and 36.7 for [tex]\theta[/tex]

[tex]Sin\theta = \frac{y}{Force}[/tex] becomes

[tex]Sin(36.7) = \frac{y}{15}[/tex]

Make y the subject

[tex]y = 15 * Sin(36.7)[/tex]

[tex]y = 15 * 0.5976[/tex]

[tex]y = 8.964N[/tex]

Calculating the x component.

Substitute 15 for Force and 36.7 for [tex]\theta[/tex]

[tex]Cos\theta = \frac{x}{Force}[/tex] becomes

[tex]Cos(36.7) = \frac{x}{15}[/tex]

Make y the subject

[tex]x = 15 * Cos(36.7)[/tex]

[tex]x = 15 * 0.8018[/tex]

[tex]x = 12.027N[/tex]

Hence, the x and y components of the force are: 8.964N and 12.027N respectively.

which apparatus Is used to determine the volume of a small block of unknown material

Answers

Options are;

A: measuring cylinder, metre rule

B: measuring cylinder, stopwatch

C: metre rule, balance

D: metre rule, stopwatch

Answer:

A: measuring cylinder, metre rule

Explanation:

Usually, when measuring volume of a small material, we make use of a piece of laboratory apparatus known as measuring cylinder which is also known as graduated cylinder.

Since it is a graduated cylinder, it means we will make use of metre rule.

Thus, the correct option is option A.

The apparatus which can be used to determine the volume of a small block of unknown material is: measuring cylinder; meter rule.

A measuring cylinder can be defined as a graduated cylinder that is typically designed and developed for the measurement of the volume of an irregularly shaped piece of object or a small block of unknown material.

Basically, a measuring cylinder is typically marked with horizontal lines on its side as units of measurement for volume.

Similarly, a meter rule refers to an apparatus that is used for the measurement of the length of an object.

Hence, the meter rule would be used in measuring the length, width and height of the small block of unknown material, in order to determine its volume while using this formula:

                            [tex]Volume =length\times width \times height[/tex]

If an airplane with a mass of 4,536 kg has gravitational potential energy of 1000 kilojoules, what is its height?

Answers

Answer:

The height is 22,472.84 m

Explanation:

Gravitational potential energy is the type of energy that is stored in the gravitational field. In other words, the gravitational potential energy as the energy that a body possesses due to the fact of being under the action of gravity, that is, the energy associated with an object subjected to force, weight, and weight is called gravitational potential energy. that is at a certain height with respect to a reference level.

The greater the weight of a body, the greater the gravitational potential energy and, considering the effect of this variable together with that of the height h at which the object is, the gravitational potential energy is:

 Ep = m*g*h

In this case:

Ep= 1,000 kJ= 1,000,000 J (being 1 kJ=1,000 J)m=4.536 kgg= 9.81 [tex]\frac{m}{s^{2} }[/tex]h=?

Replacing:

1,000,000 J=4.536 kg* 9.81 [tex]\frac{m}{s^{2} }[/tex] *h

Solving:

[tex]h=\frac{1,000,000 J}{4.536 kg*9.81\frac{m}{s^{2} } }[/tex]

h= 22,472.84 m

The height is 22,472.84 m

A steel beam is rotated in a horizontal plane to provide the centripetal acceleration for training pilots. If the pilot sits 2.19 m from the center of rotation, at what speed must he rotate in order to experience a horizontal centripetal acceleration of 65.8 m/s/s?

Answers

Given :

Pilot sits 2.19 m from the center of rotation.

Horizontal centripetal acceleration is 65.8 m/s².

To Find :

The angular velocity of the pilot .

Solution :

We know, centripetal acceleration is given by :

[tex]a = \omega^2 r\\\\\omega = \sqrt{\dfrac{a }{r}}\\\\\omega = \sqrt{\dfrac{65.8 }{2.19}}\\\\\omega = 5.48\ s^{-1}[/tex]

Hence, this is the required solution.

Explanation:

In a hydraulic lift, a 620 N force is exerted on a 0.20 m2 piston in order
to support a weight that is placed on a2.0 m2 piston. How much pressure is
exerted on the narrow piston? How much weight(force) can the wide piston lift?

Answers

Answer:

Pressure on the narrow piston = 3100 [tex]N/m^2[/tex]

The wider piston can lift the weight up-to 6200 N

Explanation:

Given that the area of the narrow piston = 0.2 [tex]m^2[/tex]

Applied force on the narrow piston, [tex]F_{in}[/tex]= 620 N

Area of the larger piston  = 2.0 [tex]m^2[/tex].

As pressure = force/ area,

So. pressure exerted on the narrow piston, [tex]P= 620/0.2=3100 N/m^2[/tex]

There is liquid in between the narrow piston and the larger piston and according to Pascal's law, the pressure inside any liquid is uniformly distributed.

As the narrow piston is applying the pressure on the liquid which is equal to the external pressure applied on the narrow piston, i.e 3100 [tex]N/m^2[/tex].

So, the uniformly distributed pressure in the fluid is 3100 [tex]N/m^2[/tex].

Now, the liquids apply pressure on the larger piston,

as force = Area x pressure, so the applied on the larger piston, [tex]F_{out}[/tex], by the liquid is

[tex]F_{out} = 3100\times2=6200[/tex] N

Hence, the wider piston can lift the weight up-to 6200 N.
