A small remote controlled car with mass 1.60 kg moves at a constant speed of V= 12.0 m/s in vertical circle inside a hollow metal cylinder that has a radius of 5.00 m. 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? B V= 12.0 m/s circle A V = 12m/s to the center of the circle at the end of circle is 5.00m
