The formula v=√64h can be used to find the velocity v in feet per second of an object that has fallen h feet. Find the velocity of an object that has fallen 25 feet. Round your answer to the nearest hundredth. a. 800 feet per second b. 200 feet per second c. 320 feet per second d. 40 feet per second

OpenStudy (sunnnystrong):

It is D. You are simply plugging in 25 for h and taking the square root of 25(64) which is 1600.
