An elevator packed with people has a mass of 1800 kg.
a) the elevator accelerates upward (in the positive direction) from rest at a rate of 1.5 m/s2 for 2.2 s. calculate the tension in the cable supporting the elevator in newtons.
b) the elevator continues upward at constant velocity for 9 s. what is the tension in the cable during this time in newtons?
c) the elevator experiences a negative acceleration at a rate of 0.65 m/s2 for 2 s. what is the tension in the cable, in newtons, during this period of negative accleration?
d) how far has the elevator moved above its original starting point in meters?
