The 2000-kg cab of a freight elevator is rated to carry a maximum load of 1200 kg, but a careless worker fills the cab with freight that has a combined inertia of 1400 kg. the worker then raises the cab 3.1 m at a steady 2.0 m> s. you notice an unfamiliar whine and come over to investigate. as supervisor, you know that the motor has a 10% tolerance in its rated power output, and you must decide whether there’s going to be trouble.
