Eric is helping a local hockey team unload hockey equipment from a very tall truck, so he uses a ramp to help unload the equipment. The ramp is at a 23.5 angle to the horizontal. Because of the ramp material and the bag material, the interface has a very high coefficient of kinetic friction of about 0.800. First, estimate the mass of a hockey bag. Use something that has a tenths place that is not zero. For example, 957 kg is not OK, but 957.1 kg works. Hopefully it is obvious those numbers are too big to be pushed. Second, pick a ramp length. It should be between 4.5-7.5 meters, but not 5.0, 6.0, or 7.0. Now answer these questions Questions: How much force does Eric need to keep the bag moving at a constant velocity? How much heat is generated by the friction on the entire trip down the ramp?
