Question

18. The distance that a freely falling object falls varies

directly as the square of the time it falls. If the object
falls 400 feet in 5 seconds, how far does it fall in 3
seconds?

Answer 1

240 feet

Explanation:

Given that,

The object falls 400 feet in 5 seconds.

We need to find how far it fall in 3 seconds.

5 seconds = 400 feet

1 second = 80 feet

So,

In 3 seconds,

d = (80×3) feet

= 240 feet

So, it will fall 240 feet in 3 seconds.
