Answer:
The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

Well it seems like this problem gives you what you need. You said the car was going 4m/s and then accelerated to 60m/s... so 4m/s would be your answer for the initial velocity
Gravity is the natural force that causes things to fall toward the earth. (down)
Sound waves are mechanical waves so they need a medium for propagation.
Explanation:
The most fundamental properties of sound waves are:-
1. Wavelength
2. Frequency
3. Amplitude
Answer:
A) 7500[N]
Explanation:
This is a problem where we have to apply the pascal principle, in this case replace the given values in the given equation:
F1 = 2500 [N]
A1 = 0.06 [m^2]
A2 = 0.18 [m^2]
![F_{2}=A_{2}*\frac{F_{1}}{A_{1}} \\F_{2}=0.18*\frac{2500}{0.06}\\ F_{2}= 7500[N]](https://tex.z-dn.net/?f=F_%7B2%7D%3DA_%7B2%7D%2A%5Cfrac%7BF_%7B1%7D%7D%7BA_%7B1%7D%7D%20%5C%5CF_%7B2%7D%3D0.18%2A%5Cfrac%7B2500%7D%7B0.06%7D%5C%5C%20F_%7B2%7D%3D%207500%5BN%5D)
