Question

The formula y = 64h gives the velocity v in feet per second of an object that has fallen h feet. Find the

velocity of an object that has fallen 92 feet. Round to the nearest hundredth.

Answer 1

The velocity of the object is 76.73 ft/sec

Explanation:

* Lets explain how to solve the problem

- The formula y = √(64h) gives the velocity y in feet per second of an

object that has fallen h feet

- To find the velocity of an object that has fallen 92 feet substitute h

by 92 in the formula

∵ y = √(64h)

∵ h = 92 feet

∴ y = √64(92) = √5888 ≅ 76.73 feet/seconds

* The velocity of the object is 76.73 ft/sec
