If a golf ball is dropped from a tall building, the distance it has fallen in feet is given by 16t2, where t is the time in seconds since the ball was dropped. How far has the ball fallen after 4 seconds?

Question

Hi, all you need to do is substitute t with 4 in the equation: f(x)=16(t)^2.
So:
f(4)=16(4)^2.
= 16(16)
= 256 feet.

It is that simple.
