  • PHysics -

    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.
