Whet net force is required to accelerate a car at a rate of 10 m/s2 if the car
has a mass of 5,000 kg?
Answer:
[tex]\boxed {\boxed {\sf 50,000 \ Newtons }}[/tex]
Explanation:
Force can be found by multiplying the mass by the acceleration.
[tex]F=m*a[/tex]
The mass of the car is 5,000 kilograms and it's acceleration is 10 meters per square second.
[tex]m= 5,000 \ kg \\a= 10 \ m/s^2[/tex]
Substitute the values into the formula.
[tex]F= 5,000 \ kg * 10 \ m/s^2[/tex]
Multiply.
[tex]F= 50,000 \ kg*m/s^2[/tex]
1 kilogram meter per square second is equal to 1 Newton. So, our answer of 50,000 kg*m/s² is equal to 50,000 Newtons[tex]F= 50,000 \ N[/tex]
A net force of 50,000 Newtons is required to accelerate a 5,000 kilogram car at 10 meters per square second.

16 kg m/s
22 kg m/s
160 kg m/s
360 kg m/s
Answer:
16 kg m/sExplanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity

What average net force is required to stop a 1950 kg car in 10.5 s if it’s initially traveling at 28m/s
Answer:
An average net force of 5200 N is needed to stop the car
Explanation:
Cinematics and Dynamics
Cinematics describes the variables involved in the movement without dealing with its causes. There are four main concepts in cinematics: Velocity (or its scalar equivalent, the speed), acceleration, time, and displacement (or the scalar equivalent, distance).
The acceleration can be calculated by:
[tex]\displaystyle a=\frac{v_f-v_o}{t}[/tex]
The initial speed is vo=28 m/s, it stops (vf=0) in t=10.5 seconds, thus the acceleration is:
[tex]\displaystyle a=\frac{0-28}{10.5}[/tex]
[tex]a = -2.67~m/s^2[/tex]
The acceleration is negative because the car loses speed.
Knowing the mass of the car m=1950 Kg, we can calculate the net force required to stop the car by using the formula:
F = m.a =1950*2.67
F = 5200 N
An average net force of 5200 N is needed to stop the car

What force must be applied to the end of a rod along the x-axis of length 2.25 m in order to produce a torque on the rod about the origin of 11 z-hat N·m? Choose among the available options below. x,y,z,-z
Answer:
4.9N approx.Explanation:
Step one:
given data
length of rod r= 2.25m
Required torque = 11 Nm
Required
The force needed to produce a torque of 11Nm
Step two:
"By definition, Torque is the twisting force that tends to cause rotation.
The point where the object rotates is known as the axis of rotation."
Mathematically,
[tex]\tau = rF\sin\theta[/tex]
[tex]\tau[/tex] = torque
r = radius
F = force
[tex]\theta[/tex] = angle between F and the lever arm
in this case is zero
[tex]\tau = rF\\\\F=\tau/r[/tex]
substituting we have
F=11/2.25
F=4.88N
F=4.9N approx.

What is an electromagnet?A coil surrounding a magnetic core through which an electric current is conducted to magnetize the core is an electromagnet. Wherever controlled magnets are needed, such as in devices where the magnetic flux needs to be adjusted, reversed, or turned on and off, an electromagnet is utilized.
The idea of the magnetic circuit systematizes the engineering design of electromagnets. The ampere-turns of the coil that creates the magnetic field and magnetic flux in the magnetic circuit are known as the magneto motive force F, or Fm, in this context.
Thus, the core is an iron nail.

Explanation:
Consider an elevator carrying Kermit the frog weighing 4000.0 N is held 5.00 m above a spring with a force constant of 8000.0 N/m. The elevator falls onto the spring while subject to a frictional force (brake) of 1000.0 N. Determine the maximum compression distance, x, of the spring.
Answer:
Maximum compression distance (x) = 2.236 m (Approx)
Explanation:
Given:
Weight of frog = 4,000 N
Height = 5 m
Constant force = 8,000 N/m
Frictional force = 1,000 N
Find:
Maximum compression distance (x)
Computation:
Using Law of conservation;
mgh = 1/2(k)(x)²
4,000(5) = 1/2(8,000)(x)²
Maximum compression distance (x) = 2.236 m (Approx)

After 4 half-lives, I ended up with 10 gram sample of
Carbon-14. What was the original amount of Carbon-14
that I started with?
Answer:
80g
Explanation:
The half - life is the time taken for half of radioactive substance to decay to half of its original composition.
After 4 half lives, the carbon - 14 sample is 10grams
Now let us trace the decay of this substance;
At the 3rd half life, it will have double the amount at the 4th half life;
2 x 10 = 20g
At the 2nd half life, there will be double the amount at the 3rd half life;
20 x 2 = 40g
Originally, we are going to have;
40 x 2 = 80g

Which of the following would increase the gravitational force of attraction between two objects?
A.-Doubling the mass of both objects, only
B.-Doubling the mass of both objects and doubling the distance between the objects
C.-Doubling the mass of one object and doubling the distance between the objects
D.-Doubling the distance between the objects, only
Answer:
Doubling the mass of both objects
Explanation:
If you double the mass of both objects, the gravitational force will quadruple, if you move the objects away from each other, the gravitational force will decrease
The gravitational force of attraction is increased by doubling the mass of both objects.
According Newton's law of Universal gravitation force, two objects in the universe attracts each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of distance between them.
[tex]F = \frac{Gm_1 m_2}{R^2}[/tex]
where;
R is the distance between the two objectsThus, we can conclude that by doubling the mass of both objects or reducing the distance between them, the gravitational force of attraction increases.
