WB7 Sledge on a slope pulled at an angle The sledge is pulled such that the angle of the rope is above horizontal and the slope is above horizontal. The sledge moves in the direction of the slope. The sledge still has weight , the Pull force remains at N and the horizontal resistance remains at . What can be worked out? challenge Suppose the child and sledge weigh about 250 N, and the Resistance force is 40 N What is the minimum Pull force needed to make the sledge + child move in each of these situations.
