Question

The distance that a free falling object falls is directly proportional to the square of the time it falls (before it hits the ground). If an object fell 52ft in 55 seconds, how far will it have fallen by the end of 9 seconds? Round your answer to the nearest integer if necessary.

Answer 1

D = kt²

55 = k(52)²

Solve fro k. Then evaluate when t = 9.
