Consider two cases, in case (a) a ball that has been thrown straight upward from the edge of a cliff. The initial speed of the ball is 20 m s-1. It goes up and then falls back down, eventually hitting the ground beneath the cliff. In case (b) the ball has been thrown straight downward at the same initial speed. In the absence of air resistance, would the ball in case (b) strike the ground with (i) smaller speed than in case (a), (ii) same speed as in case (a), or (iii) greater speed than the ball in case (a)?
