The concepts in this problem are similar to those in Multiple-Concept Example 4, except that the force doing the work in this problem is the tension in the cable. A rescue helicopter lifts a 85.1-kg person straight up by means of a cable. The person has an upward acceleration of 0.741 m/s2 and is lifted from rest through a distance of 14.2 m. (a) What is the tension in the cable? How much work is done by (b) the tension in the cable and (c) the person's weight? (d) Use the work-energy theorem and find the final speed of the person.

Question
Transcribed Image Text:The concepts in this problem are similar to those in Multiple-Concept Example 4, except that the force doing the work in this problem
is the tension in the cable. A rescue helicopter lifts a 85.1-kg person straight up by means of a cable. The person has an upward
acceleration of 0.741 m/s² and is lifted from rest through a distance of 14.2 m. (a) What is the tension in the cable? How much work is
done by (b) the tension in the cable and (c) the person's weight? (d) Use the work-energy theorem and find the final speed of the
person.
