Conservation of Linear Momentum

AI Thread Summary
In the discussion on the conservation of linear momentum, a scenario is presented where a ball strikes the ground at a speed of 45 m/sec and an angle of 80 degrees, bouncing off at a 58-degree angle. The coefficient of restitution is unspecified. The main inquiry focuses on whether the x-component of the ball's velocity remains unchanged before and after the collision, assuming the x-axis aligns with the ground and air resistance is negligible. The consensus is that, under these conditions, the x-component of velocity does remain the same. This highlights the principle of conservation of momentum in the horizontal direction during the collision.

Homework Statement



There is a ball that's going 45 m/sec and it's hitting the ground at an 80 degree angle, but when it bounces off, it has a 58 degree angle. The coefficient of restitution is not known.


Homework Equations





The Attempt at a Solution



I'm just wondering, but is the x-component of the velocity the same before the collision as afterwards if the x-axis is the ground?

With negligible air resistance, I'd say yes.
 
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...
