Question

Diego pulls a 4.5 kg sled across level snow with a force, F, of 200 N on a rope that is 35.0° above the horizontal, as shown in Figure 10-18. If the sled moves a distance of 63.6 m, how much work does Diego do?

Answer 1

The component of force in the direction of the movement is 200cos35

multiply that by the distance, and you have the work in joules.

Answer 2
