The distance an object falls is directly proportional to the square of the time
it has been falling.
After 6 seconds it has fallen 1296 feet.
How long will it take to 2304 feet? Please show all work.
:
Use a ratio equation
Let t = time to fall to 2304 ft
=
=
Cross multiply:
1296t^2 = 36*2304
:
1296t^2 = 82944
t^2 =
t^2 = 64
t =
t = 8 seconds
