Question

A supply plane needs to drop a package of food to scientists working on a glacier in Greenland. The plane flies 120 above the glacier at a speed of 120 . How far short of the target should the plane drop its cargo?

Answer 1

initial velocity of package = that of plane. Angle of projection = 0. y is known. Try solving the projectile motion equations, you'll get it. Convey doubts if any.
