Solve the all parts of given problem:

Problem: A rescue helicopter lifts a 73.1-kg person straight up by means of a cable. The person has an upward acceleration of 0.614 m/s2 and is lifted from rest through a distance of 8.10 m.

Part A: What is the tension in the cable?

Part B: How much work is done by the tension in the cable?

Part C: How much work is done by the person's weight?

Part D: Use the work-energy theorem and find the final speed of the person.

I want help to find how much work is done by the tension in the cable.
