Impulse Momentum

AI Thread Summary

Momentum is not conserved from the perspective of the falling ball because it experiences an external force, gravity, which alters its momentum as it accelerates towards the ground. To define a system where momentum is conserved, one could consider the ball and the Earth as a closed system, where the momentum lost by the ball is gained by the Earth, keeping the total momentum constant. The discussion emphasizes the importance of identifying the system boundaries when analyzing momentum conservation. Understanding these concepts is crucial for grasping the principles of physics related to motion and forces. Overall, the conversation highlights the distinction between isolated systems and those influenced by external forces.

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'

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
