Question

A sled which has a mass of 45kg is sitting on a horizontal surface. A force of 120 N is applied to a rope attached to the front of the sled such that the angle between the front of the sled and the horizontal is 35 degrees. As a result of the application of this force the sled is pulled a distance of 500m at a constant speed. How much work was done to this sled by the applied force? (49,100J)
force component in direction of motion = 120 cos 35 = 98.3 N

98.3 * 500 = 49,149 N
54
