A 1200 kg car is traveling 21.1 m/s. It collides with a stationary car of mass 1500 kg, and the two vehicles lock together. What is the speed of the combined cars immediately after the collision?
A) 7.5 m/s
B) 16.5 m/s
C) 9.4 m/s
D) 11.8 m/s
Answer:
C) 9.4 m/s
Explanation:
[tex]m_1[/tex] = Mass of moving car = 1200 kg
[tex]u_1[/tex] = Initial velocity of moving car = 21.1 m/s
[tex]m_2[/tex] = Mass of stationary car = 1500 kg
[tex]u_2[/tex] = Initial velocity of stationary car = 0
v = Velocity of the combined cars
As the momentum in the system is conserved we have
[tex]m_1u_1+m_2u_2=(m_1+m_2)v\\\Rightarrow v=\dfrac{m_1u_1+m_2u_2}{m_1+m_2}\\\Rightarrow v=\dfrac{1200\times 21.1+1500\times0}{1200+1500}\\\Rightarrow v=9.378\approx 9.4\ \text{m/s}[/tex]
The velocity of the combined mass is 9.4 m/s.

An airplane is attempting to drop relief supplies to a village. If the plane is flying at an altitude of 500m and a speed of 110 m/s, how far ahead of the drop zone does he need to release the pallet?'
Answer:
1111 m
Explanation:
The following data were obtained from the question:
Height (h) = 500 m
Horizontal velocity (u) = 110 m/s
Horizontal distance (s) =?
Next we shall determine the time taken for the pallet to get to the target. This can be obtained as follow:
Height (h) = 500 m
Acceleration due to gravity (g) = 9.8 m/s²
Time (t) =?
h = ½gt²
500 = ½ × 9.8 × t²
500 = 4.9 × t²
Divide both side by 4.9
t² = 500/4.9
Take the square root of both side.
t = √(500/4.9)
t = 10.1 s
Finally, we shall determine how far the pallet needs to be dropped in order to get to the target. This can be obtained as follow:
Horizontal velocity (u) = 110 m/s
Time (t) = 10.1 s
Horizontal distance (s) =?
s = ut
s = 110 × 10.1
s = 1111 m
Thus, the pallet must be dropped at a distance of 1111 m from the plane in order to get the target.

Una fuerza 600 N se aplica el piston pequeño de una prensa hidraulica cuyo diametro es 6 cm ¿Cual debera ser el diametro del piston grande prar que pueda levantar una carga de 350 kg?
Responder:
0.15 m
Explicación:
Paso uno:
dado
Fuerza F = 600N
diámetro d1- 6cm am = 0.06m
A1 = πd1 ^ 2/4 = 3.142 * 0.06 ^ 2/4
= 0,002 m ^ 2
Carga L = 350 kg a newton = 350 * 10 = 3500N
A2 =?
Segundo paso:
sabemos que la presión aplicada a un extremo para levantar una carga en el otro extremo se expresa matemáticamente como
F1 / A1 = F2 / A
sustituir
600 / 0.002 = 3500 / A
cruzar multiplicar
A2 = 0.002 * 3500/600
A2 = 9.89 / 600
A2 = 0.02
sabemos que área = πd ^ 2/4
0.02 = πd2 ^ 2/4
0.02 = 3.142 * d2 ^ 2/4
0.02 * 4 / 3.142 = d2 ^ 2
0.025 = d ^ 2
d = √0.025
d = 0,15 m
el diámetro debe ser de 0.15 m
Why does fulcrum placement matter for how a lever works?
Answer:
The mechanical advantage of using a lever is affected by the distance between the effort and the fulcrum and by the placement of the load. ... When the fulcrum is centered between the load and the lift, the amount of effort exerted to push down on the lever equals the amount of the load being lifted on the other end.

A car increase velocity from 30 m/s to 60 m/s in 4 seconds
Answer:
Acceleration = 7.5
Explanation:
Vf = 60m/s
Vi = 30m/s
t = 4s
[tex]Acceleration = \frac{Velocity Change}{Time Change}\\ a = \frac{60m/s-30m/s}{4s}\\ a = \frac{30m/s}{4s}\\ a = 7.5m/s^2\\ or a = 8m/s^2[/tex]

A rocket ship going from Earth to the moon must leave the___ ___ of Earth due to its mass.
Check it
The force which acts vertically downward and tends to opposite vertical upward motion of objects. Hence, the rocket ship must leave the gravitational pull of the earth due to its mass.
The magnetic field of the earth refers to the region of space around a magnet. Hence, the magnetic field of the earth has no effect on the rocket. The gravitational pull of the earth will tend to pull the rocket ship downwards until it escapes the gravitational field of the earth.Therefore, the rocket ship must leave the gravitational pull of the earth due to its mass.

Why are scientists currently debating on whether viruses are alive or not?
I NEED AN ANSWER ASAP!!!!
They are because they don't know if viruses are alive and have a mind of its own or its just humans spreading it all around. Another reason is if they do find out they are alive or not they need to find solutions to kill them or to slow/stop the spreading.
A pinball launcher is a spring with spring constant k = 65.0 N/m. It is compressed a distance of 8.00 cm and a ball of mass 0.100 kg is placed in front of it. When the spring is released, the ball rolls up the incline of the pinball machine. Assuming that it does not hit anything and that no energy is lost to friction, what vertical height does the ball gain before coming momentarily to rest?
Answer:
The maximum height reached by the ball is 0.212 meters (21.2 centimeters).
Explanation:
In this case, the ball receives a potential energy from deformed spring and reaches its maximum height at the expense of such energy. By Principle of Energy Conservation, we define the phenomenon on the ball by the following model:
[tex]U_{k,1}+U_{g,1} = U_{k,2}+U_{g,2}[/tex] (1)
Where:
[tex]U_{k,1}[/tex], [tex]U_{k,2}[/tex] - Initial and final elastic potential energies, measured in joules.
[tex]U_{g,1}[/tex], [tex]U_{g,2}[/tex] - Initial and final gravitational potential energies, measured in joules.
By definitions of elastic and gravitational potential energies, we expand and simplify the equation above as follows:
[tex]\frac{1}{2}\cdot k\cdot x^{2} = m\cdot g \cdot \Delta y[/tex] (2)
Where:
[tex]m[/tex] - Mass of the ball, measured in kilograms.
[tex]g[/tex] - Gravitational acceleration, measured in meters per square second. .
[tex]\Delta y[/tex] - Height reached by the ball, measured in meters.
[tex]k[/tex] - Spring constant, measured in newtons per meter.
[tex]x[/tex] - Spring deformation, measured in meters.
If we know that [tex]k = 65\,\frac{N}{m}[/tex], [tex]x = 0.08\,m[/tex], [tex]m = 0.1\,kg[/tex] and [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], then the maximum height reached by the ball is:
[tex]\Delta y = \frac{k\cdot x^{2}}{2\cdot m\cdot g}[/tex] (2)
[tex]\Delta y = \frac{\left(65\,\frac{N}{m} \right)\cdot \left(0.08\,m\right)^{2}}{2\cdot (0.1\,kg)\cdot \left(9.807\,\frac{m}{s^{2}} \right)}[/tex]
[tex]\Delta y = 0.212\,m[/tex]
The maximum height reached by the ball is 0.212 meters (21.2 centimeters).
