A 1000 kg roller coaster starts from rest at height H= 25 m above the bottom of a 14 m diameter loop. If the friction betwen the car and the track is negligbe, determine the speed of the car when the upside-down car is at the top of the loop. What is the downward force of the track on the car at the top of the loop?
