Projectile Motion: Understanding Initial and Final Velocities

AI Thread Summary
In projectile motion, neglecting air resistance, the initial horizontal velocity of a projectile is equal to its final horizontal velocity. This is because no horizontal forces act on the object after it is thrown, allowing it to maintain a constant horizontal speed. The lack of air resistance means that the projectile's horizontal motion is unaffected by any external forces. Understanding this concept is crucial for analyzing projectile motion effectively. Mastery of these principles will aid in self-teaching the topic.

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...
