Question
Transcribed Image Text:In the design of a supermarket, there are to be several ramps connecting different parts of the store. Customers
will have to push grocery carts up to the ramps. An engineer has done a survey and found that almost no one
complains if the force is no more than 50 N. With slope 0 =
5°, what force must a person exert, assuming a 25-
kg grocery cart (full of groceries)? Assume friction (wheels against ground, wheel on the axis and so on), can be
accounted for by a coefficient µk = 0.10.
