Question

Diego pulls a 4.5 kg sled across level snow with a force, F, of 230 N on a rope that is 35.0° above the horizontal. If the sled moves a distance of 65.5 m, how much work does Diego do?

what formula do i use?

Answer 1

The work that he performs is, by definition, the product of the force component along the direction of motion, 230 cos 35 N, and the distance moves, 65.5 m. The mass of the sled does not matter.

Answer 2

thank you soooo much!
