The rate of change of the downward velocity of a falling object is the acceleration of gravity (10 meters/sec^2) minus the acceleration due to air resistance. suppose that the acceleration due to air resistance is 0.1 inverse seconds times the downward velocity. write the initial value problem and the solution for the downward velocity for an object that is dropped (not thrown) from a great height.

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.
