Question

The distance a falling object travels towards the earth is directly proportional to the square of the time that it falls. If an orange bowl 16 feet in four seconds how far will it fall in eight seconds

Answer 1

64ft

Explanation:

d = distance from the Earth/ft

t = time falling/s

d ∝ t²

d = kt²

d = 16 and t = 4:

16 = k(4)²

16 = 16k

k = ¹⁶/₁₆

k = 1

d = t²

t = 8:

d = (8)²

d = 64
