A man uses 170N of force to lift a box with a mass 4.9 kg over his head at a constant velocity. If he is 1.9m tall then what is the net work done on the box?

Answers

The net work done on the box is 773 J. This is calculated by multiplying the force of 170 N by the distance of 1.9m that the box was lifted. Work is defined as the amount of energy transferred from a force applied against an object over a distance. In this case, the force of 170N is being applied over a distance of 1.9m, so the net work done is 170 N x 1.9 m = 773 J.
