A crane does 62,500 joules of work to lift a boulder a distance of 25.0 meters. How much did the boulder weigh?

Asked by dommanigo10

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.

The boulder weighs 2,500 newtons, which is approximately 562 pounds. This weight was calculated using the work formula, dividing the work done by the distance lifted. Therefore, the weight of the boulder corresponds to the force exerted by the crane over the distance of 25 meters.
