A 66-kg man stands on a bathroom scale inside an elevator. The scale measures in units of newtons. (a) The elevator accelerates upward from rest at a rate of 1.15 m/s2 for 1.50 s. What does the scale read during this 1.50 s interval? |N (b) The elevator continues upward at constant velocity for 8.50 s. What does the scale read now? N (c) While still moving upward, the elevator's speed decreases at a rate of 0.650 m/s² for 3.00 s. What is the scale reading during this time? N
