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