What is the Speed of the Second Ball After the Collision?

AI Thread Summary
In a head-on collision, a 0.50-kg ball traveling at 6.0 m/s collides with a 1.00-kg ball moving at 12.0 m/s in the opposite direction. After the collision, the 0.50-kg ball bounces backward at 14 m/s. The problem requires determining the speed of the second ball post-collision using collision formulas. There is a mention of a calculation error related to the expected outcome. The discussion emphasizes the need for accurate application of collision equations to solve for the unknown speed.

Homework Statement


A 0.50-kg ball that is traveling at 6.0 m/s collides head-on with a 1.00-kg ball moving in the opposite direction at a speed of 12.0 m/s. The 0.50-kg ball bounces backward at 14 m/s after the collision. Find the speed of the second ball after the collision.

hi whoopie88! :smile:

i expect you've worked it out by now, but 3 - 12 + 7 isn't 16 ! :redface:
 

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...
