The formula s 16r2 gives the distance an object falls due t

The formula s = 16r^2 gives the distance an object falls due to gravity, where s is the distance in feet and t is the time in seconds. How many feet will the object fall in 4 seconds? 256 4096 64 128 None of these is correct.

Solution

Given s = 16 t² put t = 4 in the given result s = 16 x 16 256 feet is the distance travelled in 4 seconds

Answer option (a)
