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
