Asked by kasey guilanski

A skydiver jumps out of a plane. Does the mechanical energy of the jumper change while she is falling? Ignore the effects of air resistance.

If friction is ignored, the total mechanical energy (kinetic + potential) does not change.

However, this is s stupid question. Would a skydiver jump without a parachute? You need the air resistance to stay alive.
