The formula d equals 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.
d = -16t^2
when t=2
d = -16(2^2)
d = 64 ft (neg indicates downward)
when d = 144
16t^2 = 144
t^2 = 144/16
t^2 = 9
t = sqrt%289%29
t = 3 seconds
