Nonequilibrium applications of Newton's laws of motion

In summary, a fisherman is using a 32.0-N test line while fishing from a bridge. The line can withstand a maximum force of 32.0 N without breaking. To determine the weight of the heaviest fish that can be pulled up vertically while reeling in the line with an acceleration of 2.36 m/s2, the equation 32 = m(g+a) can be used, where g is the acceleration due to gravity and a is the given acceleration. The final weight of the fish can be found by solving for m.

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 = ...?
 
  • #3
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.
 

Related to Nonequilibrium applications of Newton's laws of motion

1. What are nonequilibrium applications of Newton's laws of motion?

Nonequilibrium applications of Newton's laws of motion refer to situations where the forces acting on an object are not balanced, and the object is therefore accelerating. This can include objects in free fall, objects undergoing collisions, or objects experiencing other types of unbalanced forces.

2. How do Newton's laws of motion apply to nonequilibrium situations?

Newton's laws of motion still apply in nonequilibrium situations, but they may need to be modified or combined in order to accurately describe the acceleration and motion of an object. For example, the second law may need to be used in conjunction with the law of conservation of momentum in a collision.

3. What is an example of a nonequilibrium application of Newton's laws of motion?

One example is a ball being thrown into the air. As the ball rises, the force of gravity pulls it downwards, while the force of air resistance acts in the opposite direction. These forces are not balanced, so the ball experiences acceleration in the direction of the net force.

4. How do nonequilibrium applications of Newton's laws of motion relate to real-world situations?

Nonequilibrium applications of Newton's laws of motion are crucial in understanding and predicting the behavior of objects in the real world. They are used in fields such as engineering, physics, and even sports, to analyze and design systems that involve unbalanced forces and motion.

5. Are there any limitations to using Newton's laws of motion in nonequilibrium situations?

While Newton's laws of motion are very useful in describing the motion of objects in nonequilibrium situations, they do have their limitations. For example, they do not take into account factors such as air resistance, which can significantly affect the motion of an object. In these cases, more advanced theories, such as fluid dynamics, may need to be used to fully understand the system.
