Determine the tension of the cable.
=2900N Closer to 2906, but OK

Determine the net work done on the load.
(2900N - 2450)*23 m = 10,350 J

Determine the work done by the cable on the load.
=66700 J OK

Determine the work done by gravity on the load.
-2450*23 = 56,350 J

Determine the final speed of the load assuming it started from rest.

Solve (1/2) M V^2 = 10,350 J for V.
