5. Consider the situation where a person that has a mass of 68 kg is descending in an elevator at a constant velocity of 4.0 m/s. At some time "t", the elevator starts to slow to a stop at the rate of 2.0 m/s. a. Sketch three qualitative motion maps indicating the position, velocity and acceleration of the elevator as it descends. b. If the person in the elevator were standing on a bathroom scale calibrated in Newtons, calculate what the scale would read while the elevator was (a) descending at constant speed and (b) while slowing to a stop. c. Sketch two quantitative force diagrams (include magnitudes) for the person in the elevator as it descends at (a) constant speed and (b) during its period of acceleration.
