Two people are standing in an elevator as shown in the diagram below. The combined mass ofthe two people and the elevator car itself, m = 1150kg. The elevator car is attached to a counterweight with a mass M = 1000kg via a cable which passes through two frictionless pulleys and a motor. As the elevator and people weigh more than the counterweight, the initial acceleration ofthe elevator car is downwards. 3) Calculate the acceleratiOn of the elevator car. b) Calculate the tension in the wire. c) The motor is able to apply a force away from the elevator car and towards the counterwight block, such that the acceleration of the elevator car is zero. in this new state of mechanical equilibrium, the passengers then move at a constant velocity. In this new system: i) What is the magnitude the force applied by the motor? ii) What is the new tension in the wire
