(a)
Total tension
= tension due to mass + tension due to acceleration
= mg + ma
(b)
tension at uniform velocity
= tension due to mass only
= mg
A rescue helicopter is lifting a man (weight = 868 N) from a capsized boat by means of a cable and harness. (a) What is the tension in the cable when the man is given an initial upward acceleration of 1.83 m/s2? (b) What is the tension during the remainder of the rescue when he is pulled upward at a constant velocity?
I found the first tension= 1030.90N, however I am stuck on trying to figure out the other one. Please help!
