In the design of a supermarket, there are to be several rampsconnecting different parts of the store. Customers will haveto push grocery carts up the ramps and it is desirable thatthis not be too difficult. The engineer has done a survey andfound that almost no one complains if the force requiredis no more than 18 N. Ignoring friction, at what maximumangle θ should the ramps be built, assuming a full 25-kg cart?

Two boxes (Box A = 9.7 kg and Box B = 5.4 kg) are connected by acord running over a pulley. The coefficient of kinetic friction betweenbox A and the table is 0.18. We ignore the mass of the cord and pulleyand any friction in the pulley, which means we can assume that a forceapplied to one end of the cord will have the same magnitude at theother end. We wish to find the tension of the cord while accelerating (inN), assuming the cord doesn’t stretch. As box B moves down, box Amoves to the right. Hint: Solve for the acceleration of the system first.
