A mass of 400kg moves 27 metres with a force of 54N. What is the work produced?
- 2916J.
- 729 J.
- 1458J.
Explanation from PART66Online
Work equals force times distance: 54 N x 27 m = 1458 J. The mass of 400 kg is a distractor that is not needed, since work done by the given force depends only on that force and the distance moved.

Work= Force*Distance
W=54*27
W=1458 Joules
W=54*27
W=1458 Joules
