The formula y=square root 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 tenth.

physic PLEASE I REALLY NEED HELP WITH THIS PROBLEM 
Steve,
v = √64h
plug in 25 for h:
v = √(64*25) = 8*5 = 40
