You can put this solution on YOUR website! The distance, d, a ball will roll down an inclined plane is directly proportional to the square of the time, t. If the ball rolls 8 ft in 2 seconds, how far will it roll in 4 seconds?
-----------
d = kt^2 (k = a constant)
8 = k^2^2 = 4k
k = 2
-----
s = 2*4^2
s = 32 ft in 4 seconds
