A stone thrown upward from the top of a 88 ft cliff at 117 ft/s eventually falls to the beach below. (For this problem take the acceleration due to gravity to be 9 : 32 ft / 52; take upwards to be a positive direction.) (a) How long does the stone take to reach its highest point? time = (include units) (b) What is its maximum height? height = (include units) (c) How long before the stone hits the beach? time = (include units) ((1) What is the velocity of the stone on impact? velocity = (include units)
