The formula v =sqrt 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 75 feet. Round to the nearest tenth.,
I think first that the 64 h should be in parantheses so v=sqrt(v*h) where sqrt means square root.
If it falls 75 feet, then here h is 75 ft.
Then v=sqrt(64*75)=sqrt (4800)=69.282.
Rounded to the nearest tenth our answer would be 69.3 ft/sec.
