In the elevator shaft, a ball is thrown vertically upward with an initial velocity of 20 m/s from a height of 10 m above the ground. At the same instant, an open-platform elevator passes the 4-m level, moving upward with a constant velocity of 3 m/s. Determine (a) when and where the ball hits the elevator (b) the relative velocity of the ball with respect to the elevator when the ball hits the elevator
