(1 of 8)Assume you are on a planet similar to Earth where the acceleration of gravity is approxi- mately 10 m/s2 and the positive directions for displacement, velocity, and acceleration are upward. At time t = 0 s, an elevator is at a displace- ment of x = 0 m with a velocity of v = 0 m/s. A student whose normal weight is 400 N stands on a scale in an elevator and records the scale reading as a function of time. The data are shown in the graph.
