    Collision Wall
AI Thread Summary
The discussion revolves around solving a physics problem involving two identical spheres, one moving and one at rest, colliding on a horizontal table near a vertical wall. The goal is to determine the distance from the wall of the next impact between the spheres, expressed in terms of the initial distance d and the coefficient of restitution e. The user has attempted to apply the equations of conservation of momentum and the coefficient of restitution but is struggling with the calculations. Participants in the thread encourage sharing detailed workings to clarify the confusion and assist in finding the correct final velocities of the spheres. The conversation emphasizes the importance of accurately applying the equations to solve the problem effectively.

Homework Statement



'A small smooth sphere moves on a horizontal table and strikes an identical sphere lying at rest on the table at a distance d from a vertical wall, the impact being along the line of centres and perpendicular to the wall. Find the distance from the wall of the next impact between the spheres in terms of d and e where e is the coefficient of restitution for all the impacts involved.'

Homework Equations

The Attempt at a Solution


I have tried using e(u1- u2) = v2 - v1
conservation of momentum: u1 = v1 + v2
but got into a bit of a mess. Any help would be greatly appreciated.

You have two equations and two unknowns, the final velocities of the two balls. Can you find what they are? You also need to fix the coefficient of restitution equation to conform to this problem.

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
