Which block falls off the table first? - Elastic collision

AI Thread Summary
In the discussion, a 2kg block on a frictionless table is struck by a 1kg block traveling at 4 m/s in an elastic collision scenario. The problem involves calculating the velocities of both blocks post-collision to determine which will fall off the table first. The user has successfully calculated the initial momentum but struggles with finding the final velocities. Key equations mentioned include momentum (p=mv) and kinetic energy (1/2mv^2), which are essential for solving the problem. The focus remains on understanding the outcomes of the elastic collision to predict the movement of the blocks.

Homework Statement



A 2kg block is resting on a frictionless table. It is hit, head on, by a 1kg block heading at 4 m/s. The larger block is sitting 3m from the edge of a 5m long table. The collision happens with the smaller block's distance being 2m from the table and the larger blocks d = 3m from edge. Which block will fall off the table first? It's an elastic collision.

Homework Equations



I used p=mv and 1/2mv^2

The Attempt at a Solution



I was able to fine the momentum before, but I can't solve for the velocities.

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...
