Calculating Collision Speeds: Billiard Ball Physics Homework Solution

AI Thread Summary
To solve for the speed of ball 2 after the collision, use the conservation of momentum principle, which states that the total momentum before the collision equals the total momentum after. Given that ball 1 has an initial speed of 5.00 m/s and moves at 4.35 m/s after the collision, the momentum equation can be set up as m1v1_initial + m2v2_initial = m1v1_final + m2v2_final. Since ball 2 is initially stationary, its initial velocity is 0, simplifying the equation to m1(5.00) = m1(4.35) + m2(v2_final). Solving this will yield the speed of ball 2 after the collision.

Homework Statement



A billiard ball (ball 1) moving at 5.00 m/s strikes a stationary ball (ball 2) of the same mass. After the collision, Ball 1 moves at a speed of 4.35 m/s. Find the speed of ball 2 after collision


Homework Equations



Find speed



The Attempt at a Solution



The equation I am usuing m1v1=m2v2 seems like it might fit??

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...
