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)
