Several children are on a sled pulled by a four-wheeler across a level snow-covered field. The sled is moving at a constant speed of 9. 25 m/s, and the tow rope (parallel to the ground) makes an angle of 35. 0°, with respect to the velocity of the sled.


If the tension in the rope is 42. 0 N, determine the work done (in J) on the sled by the tension in the rope in 13. 0 s
