plane is flying horizontally and at a constant velocity of 100.0 m/s above the ocean. It is to deliver cargo to a small island. The cargo is dropped from the plane when it is a horizontal distance of 300.0 m away from the landing site of the cargo. Ignore air resistance.

a) At what height above the ground is the plane flying? Use g = 9.8 m/s^2

b)Referring to the Plane Question, what is the sign of the vertical displacement of the cargo as it goes from the plane to the island?
