Abird flies off of a cliff, dropping a feather and knocking rocks off the cliff. the rocks reach the ground much faster than the feather. which energy transformations occur in this case? check all that apply. all of the rocks’ potential energy is converted into kinetic energy because rocks do not experience wind resistance. some of the potential energy of the feather is converted into kinetic energy. all of the feather’s potential energy is converted into thermal energy due to the friction of air resistance. some of the rocks’ potential energy is converted into thermal energy due to the friction of air resistance. some of the feather’s potential energy is converted into thermal energy due to the friction of air resistance.

Ahot-air balloonist, rising vertically with a constant speed of 5.00 m/s releases a sandbag at the instant the balloon is 40.0 m above the ground. after it is released, the sandbag encounters no appreciable air drag. compute the velocity of the sandbag at 0.250 s after its release.
