A rock is dropped from the edge of a cliff that is 214 meter above the water. Determine the position and veloctiy of the rock (use s(t)=-4.9t2+vot+so). Then determine the average velocity on the interval [2,5] and find the instantaneous velocity when t=2 seconds and t=5 seconds. Finally find teh time the rock hits the surface of the water and the velocity at impact.
