Problema Solution

The formula d=16t^2 is Galileo's formula for freely falling objects. The distance d in feet an object falls depends on the time elapsed t in seconds. Use Galileo's formula and complete the following table.

t in seconds 3 blank

d in feet blank 256

Answer provided by our tutors

for t = 3 sec we have


d = 16*3^2


d = 144 ft



for d = 256 ft we have


16t^2 = 256


t^2 = 256/16


t^2 = 16


t = 4 sec
