After a trip to the store a 70.0-kg person is carrying heavy bags perpendicular to the direction of motion. How much work is being done by the person on the bags? Use the definition of work to show your result.
b) He takes a rest on a bench and leaves his bags on the ground. Sketch a free-body diagram for each of the three objects shown in the Figure.
c) Once he gets back to his apartment building he takes an elevator up. What acceleration of the elevator is necessary for his weight to increase by 10.0%?

17) To get up on the roof, a person (mass 70.0 kg) places a
6.00-m aluminum ladder (mass 10.0 kg) against the house on a
concrete pad with the base of the ladder 2.00 m from the house. The
ladder rests against a plastic rain gutter, which we can assume to
be frictionless. The center of mass of the ladder is 2 m from the
bottom. The person is standing 3 m from the bottom. What are the
magnitudes of...
