Question

A crane dose 62500 joules of work to lift the boulder distance of 25 meters how much does the boulder way

Answer 1

Work is equal to force times distance.
-W=F*D or W=FD
Where force is measured in Newtons(N) and distance in meters(m). The unit for work is a newton-meter (aka joule(j))
All you have to do to find how much it weighs is do the opposite. So you would do 62500j/25m. That gives you 2500N, to check it you just multiply 2500N and 25m. Which gives you 62500j.
Hope this helped!

Answer 2

Work = force x distance
62,500 joules = boulder's weight x 25 meters
Divide each side by 25 meters:
Boulder's weight = 62,500 joules / 25 meters = 2,500 newtons
That's about 562 pounds
