72. A fisherman is fishing from a bridge and is using a “45-N test line.” In other words, the line will sustain a maximum force of 45 N without breaking. What is the weight of the heaviest fish that can be pulled up vertically when the line is reeled in (a) at a constant speed and (b) with an acceleration whose magnitude is 2.0 m/s2?

 

Now solve for W

For no acceleration

 

For acceleration equal to 2.0 m/s2

 

 

  No acceleration

  accelerating at 2 m/s2
