A rescue helicopter is lifting a man (weight = 925 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 2.59 m/s2? (b) What is the tension during the remainder of the rescue when he is pulled upward at a constant velocity?

  • physics -

    1) ma=T-mg
    T=m(a+g)
    2) a=0
    =>
    0=T-mg
    T=mg
