A stone was dropped off a cliff and hit the ground with a speed of 152 ft/s. What is the height of the cliff? (Use 32 ft/s for the acceleration due to gravity.) Step 1 We know that s(t) = _at + Vot + So, where s(t) = 0 is ground level and the positive direction is up. In this situation, we have a = 4.75 * ft/ s2 , VO = 361 X ft/s, and so = h, where h is the height of the cliff (in feet) that we wish to find.
