Question

A 535 kg roller coaster car began at rest at the top of a 93.0 m hill. Now it is at the top of the first loop-de-loop. This roller coaster’s track is nearly frictionless, so resistance can be ignored. Using g = 9.8 m/s2, what best describes the roller coaster car when it is at the top of the loop-de-loop?

Answer 1

the correct answer is B on edge

Answer 2

The correct answer is The car has both potential and kinetic energy, and it is moving at 24.6 m/s.
