A small remote-control car with mass 1.60 kg moves at a constant speed of v = 12.0 m/s in a vertical circle inside a hollow metal cylinder that has a radius of 5.00 m (Figure 3). What is the magnitude of the normal force exerted on the car by the walls of the cylinder at A ) point A (at the bottom of the vertical circle) and B) point B (at the top of the vertical circle)?
