Consider a 80.0-kg man standing on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of 1.56 m/s in 0.850 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 1.80 s and comes to rest. (a) What does the spring scale register before the elevator starts to move? N (b) What does the spring scale register during the first 0.850 s? N (c) What does the spring scale register while the elevator is traveling at constant speed? N (d) What does the spring scale register during the time it is slowing down? N
