Problem
A balloon is ascending at the rate v=12 km h−1 and is being carried horizontally by the wind at vw=20 km h−1. If a ballast bag is dropped from the balloon at the instant h=50 m, determine the time needed for it to strike the ground. Assume that the bag was released from the balloon with the same velocity as the balloon. Also, find the speed with which the bag strikes the ground.
