(a) The elevator accelerates upward from rest at a rate of 1.30 m/s for 1.50 s. What does the scale read during this 1.50 s interval? 932.4 N (b) The elevator continues upward at constant velocity for 8.50 s. What does the scale read now? 823.2 N (c) While still moving upward, the elevator's speed decreases at a rate of 0.450 m/s for 3.00 s. What is the scale reading during this time? 714 X The elevator's speed is now decreasing. What is the direction of the acceleration vector now? N
