A person using a lever applies 98 Newtons to lift a 40-kilogram box. They apply the force over a distance of 8 meters to lift the box a distance of 2 meters. How much work is done?(
Work is equal to force multiplied by the distance over which the force is applied.
The force applied is 98 Newtons.
The distance over which the force is applied is 8 meters.
Therefore, work = force * distance = 98 Newtons * 8 meters = 784 Joules.
So, 784 Joules of work is done.
