Displacement crossed with velocity?

AI Thread Summary
The discussion focuses on the physical significance of the cross product of position and velocity, denoted as rXv, in the context of mechanics. It highlights that this quantity is related to the angular momentum of a particle, which is defined as the product of the position vector and linear momentum. The participants explore how rXv can provide insights into rotational motion and the conservation of angular momentum. The relationship between force, velocity, and angular momentum is emphasized, suggesting that understanding rXv can enhance comprehension of dynamic systems. Overall, the significance of rXv lies in its connection to fundamental principles of mechanics.

I was reading Kleppner and Kolenkow's An Introduction to Mechanics, and in one of the problems you're given a force vector as a fuction of time. You're given initial conditions and asked to compute velocity and position, then asked to find the cross product of position and velocity, that is rXv.

Is there any physical significance of the quantity rXv?

Consider how the angular momentum of a particle is defined.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
