Nonequilibrium applications of newton's laws of motion

  1. Oct 12, 2009 #1
    A fisherman is fishing from a bridge and is using a "32.0-N test line." In other words, the line will sustain a maximum force of 32.0 N without breaking. What is the weight of the heaviest fish that can be pulled up vertically, when the line is reeled in with an acceleration whose magnitude is 2.36 m/s2?

    I have no idea on how to go about this problem, please help!
    Thank you!

    If T is the tension in the string,
    T - mg = ....?

    Is the tensthe tension is the 32.0N-mg
    mg=a so i plugged in 2.36
    so 32-2.36=29.64
    which is wrong...

    I thought about doing it this way 2.36=[2(32)-(x*9.8)]/x but not sure if this is correct or how to solve for x.

    32 - mg = ma
    Or 32 = m(g+a). g is known and a is given.
    Find m.
