A roller coaster car of mass 800 kg when released from rest at point A (height h above the ground) slides along the track and inside the loop of radius 16.0 m. The car never loses contact with the track.
A) Draw below a free body diagram for the car the car at the top of the loop.
B) If the normal force acting on the car at the top is 1500 N, what is the speed of the car at the top of the loop?
C) if the car was released at a height 55 m and the speed at the top of the loop is 17 m/s, what is the amount of thermal energy produced by friction from the point of release to the top of the loop?

A roller coaster car has a mass of 800 kg. It is launched horizontally from a giant spring (spring constant 35 kN/m), rolls 10m and then goes through a vertical loop-the-loop track of radius 7 m. On average, for every meter the car rolls on the track, thermal energy increases by 800 J. The designer, who wants to go home for the weekend, says that compressing the spring 3 m should give the car enough energy to safely go...
