Mary spots Bill approaching the dorm at a constant rate of 2.00 m/s on the walkway that passes directly beneath Mary's window, 17.0 m above the ground. When Bill is L = 180 m away from the point below Mary's window she decides to drop an apple down to him. 1) How long should Mary wait to drop the apple if Bill is to catch it 1.79 m above the ground, without either speeding up or slowing down? 2) How far from directly below the window should Bill be when Mary releases the apple? 3)What is the angle θ between the vertical and the line of sight between Mary and Bill at the instant Mary should release the apple?
