A rescue helicopter is lifting a man (weight = 753.782235376817 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 0.691 m/s2? (b) What is the tension during the remainder of the rescue when he is pulled upward at a constant velocity?
