Transcribed Image Text:The cable of the 2000 kg elevator cab shown the figure snaps when the cab is at rest at the first floor, where the cab
bottom is a distance d = 4.5 m above a spring of spring constant k = 0.14 MN/m. A safety device clamps the cab against
guide rails so that a constant frictional force of 4.3 kN opposes the cab's motion. (Assume that the frictional force on the
cab is negligible when the cab is stationary.)
