Question
A sphere of mass 85 kg is attached to one end of a rope as shown in the figure below. It is found that the rope does an amount of work
W = 8030 J
in pulling the sphere upward through a distance 9.6 m. Find the tension in the rope.

assumeing the mass is stopped at the end of the pull.
force*distance=work
solve for force.
force*distance=work
solve for force.
I think it is 8030/9.6 = 836.453333
Backsolving: 836.4583333*9.6 = 8030
Force is 836.4583333
Backsolving: 836.4583333*9.6 = 8030
Force is 836.4583333
