A 85-kg man stands on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of 1.2 m/s in 0.72 s. The elevator travels with this constant speed for 5.0 s, undergoes a uniform negative acceleration for 1.6 s, and then 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 0.72 s of the elevator's ascent? 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 elevator's negative acceleration? N
