While an elevator of mass 2355 kg moves upward, the tension in the cable is 34.1 kN. Assume the elevator is supported by a single cable. Forces exerted by the guide rails and air resistance are negligible. If at some point in the motion the velocity of the elevator is 1.20 m/s upward, what is the upward velocity of the elevator 4.00 s later? (show work)
