Alright, so I'm a little stuck on the last bit of this problem: The cable of the 1,800 kg elevator cab snaps when the cab is at rest at the first floor, where the cab bottom is a distance d = 3.7 m above a cushioning spring whose spring constant is k = 0.15 ... Webat the first , where the cab bottom is a distance d=3.7m above a spring of spring constant k =1.5×105N/m. A safety device clamps the cab against guide rails so that a constant frictional force of 4400N opposes the cab’s motion. (a) Find the speed of the cab just before it hits the spring.
