Homework Help Overview

The problem involves a fisherman using a test line with a maximum tension of 32.0 N to pull up a fish vertically while applying an acceleration of 2.36 m/s². Participants are exploring the relationship between tension, weight, and acceleration in the context of Newton's laws of motion.

Discussion Character

  • Mixed

Approaches and Questions Raised

  • Participants are attempting to establish the relationship between tension, mass, and acceleration, questioning how to set up the equations correctly. Some are exploring the implications of the maximum tension and how it relates to the weight of the fish.

Discussion Status

There are various approaches being discussed, with participants questioning their setups and calculations. Some guidance has been offered regarding the relationships between the variables, but no consensus has been reached on the correct method or solution.

Contextual Notes

Participants are working under the constraint of the maximum tension of the line and the given acceleration, while also considering gravitational force. There is uncertainty about the correct application of Newton's laws in this scenario.

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.
