If the table is horizontal, its velocity as a function of time is given by ✓ = 1.10î - 9.80tĵ, with v in m/s and t in s.

An airplane needs to drop a package of supplies to a team in a remote location (landing is not possible). The plane is flying 112.8 m above the ground at a speed of 196.8 m/s. We know that the plane should NOT drop the package when it is passing directly over the location. Instead, the plane needs to drop the supplies BEFORE it reaches the location. How far out (in meters) should the supplies be dropped? (in other words, how far horiszontally will the package go as it falls?) Ignore air resistance.
