A rescue helicopter lifts a 90-kg person straight up by means of a cable. The person has an upward acceleration of 0.70 m/s2 and is lifted from rest through a distance of 13 m.

(a) What is the tension in the cable?

(b) How much work is done by the tension in the cable?

(d) Use the work-energy theorem and find the final speed of the person.
