1. In the design of a repository (a place to store stuff), there are to be several ramps connecting different parts of the repository. Customers will have to push carts up the ramps, and it is obviously desired that this not be too difficult. An engineer has done a survey and found that almost no one complains if the force required is no more than 50 N while moving a cart at constant velocity. Will a slope 0 = 5° be too steep, assuming a 30kg cart (full of merchandise)? Assume friction (wheels against the ground, wheel on the axles, and so on), can be accounted for by a coefficient of friction μk = 0.10.
