A rock is dropped off the edge of a cliff and its distance s (in feet) from the top of the cliff after t seconds is s(t) = 16t. Assume the distance from the top of the cliff to the water below is 1296 ft. a. When will the rock strike the water? The rock will strike the water at 9 seconds. (Simplify your answer.) b. Make a table of average velocities and approximate the velocity at which the rock strikes the water.
