A535 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?
