Homework Help: physics

Posted by Pritesh on Thursday, March 21, 2013 at 6:14pm.

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 0.80 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 a rest. What does the spring scale register: a) before the elevator starts to
move, b) during the first 0.80 s, c) while the elevator is travelling at constant speed, and d)
during the time interval it is slowing down.
