Answer:
The correct answer is 16 seconds for the body to fall 64 feets.
Explanation:
The equation of a dropped odie tu falling is given by
where d is the distance in feet and t is the time it took in seconds.
Now an object falls from 64 feet. The time it takes to fall is given by
=
⇒ t = ±
= 16.
Negative sign is neglected as time cannot be negative.
Thus it would take 16 seconds for the object to drop from 64 feets.
