Solve the all parts of given question:

Question: A 78.0 kg man stands on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of 1.61 m/s in 1.10 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 1.60 s and comes to rest.

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

________ N

Part B: What does it register during the first 1.10 s?

________ N

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

________ N

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

________ N

If possible just a brief explanation how you got the answer?
