In Example 5.8, we investigated the apparent weight of a fish in an elevator. Now consider a 72.0-kg man standing on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of 1.20 m/s in 0.800 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 1.50 s and comes to rest. What does the spring scale register (a) before the elevator starts to move, (b) during the first 0.800 s, (c) while the elevator is traveling at constant speed, and (d) during the time interval it is slowing down?

Solution Summary: The author analyzes the reading of the spring scale before the elevator starts to move.

How is it that part a is connected to part b? I can't seem to solve either part and don't see the connection between the two.
Hello, please help with inputing trial one into the equation, I just need a model for the first one so I can answer the rest. Also, does my data have the correct sigfig?
Thanks!
