A small object is released from a hot air balloon which is rising straight upwards. At the instant when the object is released, it
is located 20.0 m above the ground. An observer standing at rest on the ground below notes that just before the object
crashes into the soft ground, it (the object) is moving straight down at 21.4 m/s. Assume that air resistance is negligible,
although it would not be! In the following, consider the object's motion from the viewpoint of a person standing at rest on
the ground. Assume that the acceleration due to gravity has magnitude 9.80
