Ball Frictionless Rest Table

AI Thread Summary

A cue ball with a mass of 0.165 kg is initially at rest on a frictionless table and is struck by a pool stick, receiving an impulse of +1.50 Ns. This impulse results in the cue ball gaining a velocity calculated using the impulse-momentum theorem, where the impulse equals the change in momentum. After the cue ball collides elastically with a second ball of equal mass that is at rest, conservation of momentum and kinetic energy principles can be applied to find the velocity of the second ball post-collision. The calculations reveal that the second ball moves with the same velocity as the initial cue ball after the collision. Understanding these principles is crucial for solving similar physics problems involving collisions and impulse.

A cue ball (mass=0.165kg) is at rest on a frictionless pool table. The ball is hit dead center by a pool stick, which applies an impulse of +1.50Ns (Newton-seconds) to the ball. The ball the slides along the table and makes an elastic head-on collision with a second ball of equal mass that is initially at rest. Find the velocity of the second ball just after it is struck.

I need help at least getting started.

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:
