If a ball is dropped from from 288 ft above the ground, how long does it take to reach ground level?
The distance S for a free falling object from rest over t seconds is:
Solve for t.
solve for t.
Be cautious about units on this problem. The problem gives the distance in feet. Gravitational acceleration in English units is about 32 ft/sec^2 .
Oops. Use g=32.2 f s-2
