A hot-air balloon is traveling vertically upward at a constant speed of 5.0 m/s. When the balloon is 21 m above ground, a package is released from the balloon which eventually hits the ground directly below the balloon. Calculate the following: a. The time the package spends in the air. b. The speed of the package right before it hits the ground. c. The height of the balloon at the moment the package hits the ground.
