You can find the distance d an object falls in feet for time t in seconds using the formula d= 16t^2. Suppose a ball is dropped out of a window of a tall building. How far will the ball in 3 seconds?
a 144 ft
b 96 ft
c 48 ft
d 16 ft
plz explain how to do this? thanks !!!
d= 16*9=? The 9 is time squared.
