An 86.0-kg man stands on a bathroom scale inside an elevator. (a) The elevator accelerates upward from rest at a rate of 1.35 m/s² for t seconds. What does the scale read during this time interval? N (b) The elevator continues upward at constant velocity for t₂ seconds. What does the scale read now? N (c) While still moving upward, the elevator's speed decreases at a rate of 0.600 m/s² for t₂ seconds. What is the scale reading during this time? N
