The time (t, in seconds) for a free-falling object to fall d feet is described by the mathematical formula:

t=d over the square root of 16

If a worker accidentally drops a hammer from a building and it hit the ground 4 seconds later, from what height was the hammer dropped

sqrt(16)=4

t=d/4

t=4

4=d/4

d=16

the hammar was dropped from 16 feet

your formula for time should have been:

t = √(d/16) or d = 16t^2

when t=4, then

d = 16(4^2) = 64 feet
