A 100kg elevator carrying 4 people with average massses of 55 kg is accelerating upward at 0.8 m/s ^2. What is the tension in the cable?
E. Suppose you are standing on the scale in the elevator and the elevator is accelerating downward with an acceleration smaller than 9.8 m/s2 i. Draw free-body diagrams of yourself, the scale, and the floor of the elevator where it interacts with the scale. ii. How must the magnitude of the force exerted by the scale on you compare with your own weight? iii. How must the reading on the scale compare with the reading you make when the elevator...
