**Steve**, Monday, December 17, 2012 at 10:37ams(t) = 24t + 16t^2

s(15) = 24*15 + 16*225 = 3960 ft

So, since it fell from only 150 ft, it will fall 150 ft. And, it won't take no steenking 15 seconds to hit the water.

Even if it is thrown upward, and the rock's height is

h(t) = 150+24t-16t^2

it will hit the water in about 4 seconds.
