Consider a $76.0?\mathrm{kg}$ man standing on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of $1.82\mathrm{m}/\mathrm{s}$ in $0.850\mathrm{s}$. It travels with this constant speed for the next $5.00\mathrm{s}$. The elevator then undergoes a uniform acceleration in the negative $y$ direction for $1.20\mathrm{s}$ and comes to rest. (a) What does the spring scale register before the elevator starts to move? $?\mathrm{N}$ (b) What does the spring scale register during the first $0.850\mathrm{s}$ ? Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. N (c) What does the spring scale register while the elevator is traveling at constant speed? $?\mathrm{N}$ (d) What does the spring scale register during the time it is slowing down? Your response differs from the correct answer by more than $10\%$. Double check your calculations. N
