Question

A crate is being pushed across the floor by a student. The student exerted 40 Newtons of force over a distance of 100 meters. How much work the student do on the crate?

Answer 1

The student did 4000 Joules of work on the crate by exerting a force of 40 Newtons over a distance of 100 meters.

Step-by-step explanation:

The student did work on the crate when pushing it across the floor. The work done by a force is calculated by multiplying the force applied by the distance over which it is applied, provided that the force is applied in the direction of movement. In this case, work = force x distance = 40 Newtons x 100 meters = 4000 Joules. Therefore, the student did 4000 Joules of work on the crate.
