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 74ft

in 2
seconds, how far will it have fallen by the end of 7
seconds?

Answer 1

the object will fell 906.5 ft by the end of 7 seconds

Explanation:

distance ∝ time²

74 ∝ 4

x ∝ 49

thus, 74/4 = x/49

74 * 49 = 4x

x = 3,626/4

x = 906.5 ft
