A small remote-control car with a mass of 0.750 kg moves at a constant speed of v = 9.0 m/s in a vertical circle inside a hollow metal cylinder that has a radius of 6.00 m.
1. What is the magnitude of the normal force exerted on the car by the walls of the cylinder at point b (at the top of the vertical circle)?
2. Do you think the magnitude of the normal force from a and b are the same
