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: 2 and blank
d in feet: blank and 400
Answer provided by our tutors
t in seconds: 2 and 64.
d=16*2^2=64.
d in feet: 5 and 400
t^2=400/16.
t=20/4
