Question

The distance d in feet that dropped objects falls in t seconds is given byt he equation d ÷ 16 = t^2. How long does it take a dropped object to fall 64 feet?

Answer 1

2 seconds

Explanation:

You have to first substitute d for 64 because the distance it dropped is 64ft:

64 ÷ 16 =
`t^(2)`

Now, simplify the right side:

4 =
`t^(2)`

Finally, take the square root of both side:

`\sqrt{t^(2) }` =
`√(4)`

t = 2

Since time is in seconds, this means that it took 2 seconds.
