**MathMate**, Thursday, August 26, 2010 at 10:26pmThe distance S for a free falling object from rest over t seconds is:

S=(1/2)gt²

where

g=9.8 m.s^{-2}

S=288m

Solve for t.

solve for t.

**Quidditch**, Thursday, August 26, 2010 at 10:53pmBe cautious about units on this problem. The problem gives the distance in feet. Gravitational acceleration in English units is about 32 ft/sec^2 .

^{-2}

Thanks Qudditch.
