Question
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 9.00 m/s, and the tow rope (parallel to the ground) makes an angle of 35.0
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 9.00 m/s, and the tow rope (parallel to the ground) makes an angle of 35.0 degree with respect to the velocity of the sled (see the figure below). If the tension in the rope is 44.0 N, determine the work done on the sled by the tension in the rope in 12.5 s.Explanation / Answer
the distance = velocity X time ........... ( zero acceleration)
s= 9X 12.5 = 112.5 m
w= F cos theta X 112.5 4054.8 J
