An elevator filled with passengers has a mass of 1.70×103kg. (a) the elevator accelerates upward from rest at a rate of 1.20m/s2 for 1.50 s. calculate the tension in the cable supporting the elevator. (b) the elevator continues upward at constant velocity for 8.50 s. what is the tension in the cable during this time? (c) the elevator decelerates at a rate of 0.600m/s2 for 3.00 s. what is the tension in the cable during deceleration? (d) how high has the elevator moved above its original starting point, and what is its final velocity?

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?
