Angular momentum linear momentum

AI Thread Summary
Hitting a ball with a baseball bat at its far end demonstrates the translation of angular momentum into linear momentum, as the bat stops spinning while the ball gains momentum. To translate angular momentum to linear momentum, one must consider the forces applied and the point of impact. The ball possesses angular momentum relative to the hands, and without external muscle force, the bat will continue to rotate. Understanding this relationship is crucial for effective hitting techniques in baseball. The discussion highlights the interplay between angular and linear momentum in sports dynamics.

Hi all,

If one were to hit a ball with a baseball bat on the far end of the bat, you could say that angular momentum is translated to linear momentum.(bat stops spinning, ball gains momentum).

how do i translate angular momentum to linear momentum?

thanks

Relative to your hands the ball does have angular momentum, additionally unless your muscles exert some external force on the bat it more than likely will continue to rotate.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
