Aball is thrown vertically upward with an initial speed of 18 m/s. then, 0.73 s later, a stone is thrown straight up (from the same initial height as the ball) with an initial speed of 30 m/s. how far above the release point will the ball and stone pass each other? the acceleration of gravity is 9.8 m/s 2 . answer in units of m.
