The physics of weight on the earth and Mars. (conceptual) 1. Object A weighs twice as much as object B at the same spot on the earth. Would the same be true at a given spot on Mars? Account for your answer. The physics of real and apparent weight, cable tension, and the elevator. 2. An elevator, complete with contents, has a mass of 2000.0 kg. For each of the two situations described in a) and b) below, do the following. Draw a free-body diagram showing the correct relative lengths of the Tand the Fo vectors. Determine the value of 7 (the tension in the elevator cable). State the value of the real weight and the apparent weight in each case. o a. The elevator is moving up at a constant velocity of 2.0 m/s. o b. The elevator is moving up at a constant acceleration of 1.0 m/s2
