If zak's speed is 3.00 m/s when he starts to slide, what distance d will he slide before stopping? express your answer in meters.

A single mass (m1 = 4.4 kg) hangs from a spring in a motionless elevator. The spring constant is k = 275 N/m. Now, three masses (m1 = 4.4 kg, m2 = 13.2 kg and m3 = 8.8) hang from three identical springs in a motionless elevator.
