A 75-kg person stands on a weight scale in an elevator and pushes the button to go up. The elevator accelerates upward at 3 m/s2, then rises at a steady speed of 15 m/s, and finally decelerates at the top floor at a rate of 2 m/s2. Match the force values to their descriptions. Some values may be used more than once, and some may not be used at all. 1. person's weight during upward acceleration 2. scale reading during...

A 72 kg man stands on a bathroom scale in an elevator. Starting from rest at the top floor, the elevator descends, attaining its maximum speed of 1.20 m/s in 0.80 s. It travels with this constant speed for the next 5.00 s. The elevator then slows down for 1.50 s and comes to rest at ground level. a)What is the acceleration of the man during the first 0.80 s? Answer in units of m/s2 and use the upward direction...
