You bring a bathroom scale onto an elevator and press "up". Your mass is 65 kg. If the bathroom scale reads 750 N, (a) what is the acceleration of the elevator? You then press down and the acceleration downward is of the same magnitude. (b) While accelerating downward, you hold a small mass of 100 g attached to a string. What is the tension in the string? This elevator is in the new BU Data Science building where g = 10 m/s². Your work should include free body diagrams
