Integrated concepts. An elevator filled with passengers has a mass of 1700 kg.
(a) The elevator accelerates upward from rest at a rate of 1.20 m/s2 for 1.50 s. Calculate the tension in the cable supporting the elevator.
(b) The elevator continues upward at a constant velocity for 8.50 s. What is the tension in the cable during this time?
(c) The elevator decelerates at a rate of 0.600 m/s2 for 3.00 s. What is the tension in the cable during deceleration?
(d) How high has the elevator move above its original starting point, what is its final velocity?
