Magnitude of final velocity. Due today

AI Thread Summary
The discussion revolves around calculating the final velocities of two gliders after an elastic collision. The first glider has a mass of 0.143 kg and an initial speed of 0.750 m/s, while the second glider has a mass of 0.303 kg and an initial speed of 2.13 m/s in the opposite direction. Participants are seeking guidance on applying the conservation of momentum and kinetic energy equations to find the post-collision velocities. The significance of the elastic collision is highlighted, emphasizing that both momentum and kinetic energy are conserved. The conversation aims to clarify the steps needed to solve the problem effectively.

Homework Statement



A glider of mass 0.143 kg is moving to the right on a frictionless, horizontal air track with a speed of 0.750 m/s. It has a head-on collision with a glider 0.303kg that is moving to the left with a speed of 2.13 m/s. Suppose the collision is elastic.

Homework Equations


MaVa1+MbVb1=MaVa2+MbVb2
1/2MaVa1^2+1/2MbVb1^2=1/2MaVa2^2+1/2MbVb2^2


The Attempt at a Solution



Where do I start with this? I have all of the left side of the equations, but nothing on the right

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...
