Problem The formula $v = \sqrt{2gh}$ give the velocity, in feet per second, of an object when it falls h feet accelerated by gravity g, in feet per second squared. If g is approximately 32 feet per second squared, find how far an object has fallen if its velocity is 80 feet per second.

Answer Key

Solution

$h = \dfrac{80^2}{2(32)}$

$h = 100 ~ \text{ft}$
