In a "worst-case" design scenario, a 2000-{\rm kg} elevator with broken cables is falling at 4.00{\rm m/s} when it first contacts a cushioning spring at thebottom of the shaft. the spring is supposed to stop the elevator, compressing 2.00 {\rm m} as it does so. during the motion a safety clampapplies a constant 17000-{\rm n} frictional force to the elevator.1. what is the speed of the elevator after it has moveddownward 1.00 {\rm m} from the point where it first contacts aspring? 2. when the elevator is 1.00 {\rm m} below point where it first contacts a spring, whatis its acceleration?
