SP5. A sled and rider with a total mass of 50 kg are perched at the top of a hill, as pictured in the diagram. The top of this hill is 42 m above the low point in the path of the sled. A second hump in the hill is 28 m above this low point. Sup- pose we also know that approximately 3600 J of work is done against friction as the sled travels between these two points. 42 m a. Will the sled make it to the top of the second hump if no kinetic energy is given to the sled at the start of its mo- tion? Explain. b. What is the maximum height that the second hump can be in order for the sled to reach the top, assuming that the same work against friction will be involved and that no initial push is provided? Explain. 28 m SP5 Diagram
