Compute all parts of given problem:

Problem: Consider a 76.0-kg man standing on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of 1.94 m/s in 0.750 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 1.40 s and comes to rest.

Part A: What does the spring scale register before the elevator starts to move?

Part B: What does the spring scale register during the first 0.750 s?

Part C: What does the spring scale register while the elevator is traveling at constant speed?

Part D: What does the spring scale register during the time it is slowing down?
