Tutorial Exercise Consider a 75.5-kg man standing on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of 1.93 m/s in 0.525 s. It travels with this constant speed for the next 5.00 s. The elevator then undergoes a uniform acceleration in the negative y direction for 1.95 s and comes to rest. (a) What does the spring scale register before the...
