The 40 kg wheel of an airplane flying at 248 m/s at an altitude of 7400 m falls off during a flight.

If the wheel hits the ground at 377 m/s, how much work was done on the wheel by air resistance (drag) during its fall?

If there had been no drag, what would have been the wheel's speed when it hit the ground?
