Friction Coefficient Homework: Find Speed of Block

AI Thread Summary
The discussion revolves around a physics homework problem involving a 25.0 kg block released from a height of 3.00 meters on a frictionless ramp, encountering friction between points B and C. The main challenges include determining the coefficient of friction on the rough section and subsequently calculating the block's speed at point C. Participants express difficulty in finding the coefficient of friction, suggesting that additional information may be needed to solve the problem effectively. Once the coefficient is established, calculating the block's speed is expected to be straightforward. The conversation highlights the importance of understanding friction in motion dynamics.

Homework Statement


A 25.0 kg block is released from point A (on a ramp, think of a skateboarders half pipe) at 3.00 meters. The track is frictionless except from points B to C (which has a length of 6m). The block travels down the track from point A to B, at which point it hits the friction section and travels to C.

Question 1: Determine the coefficient of friction between the block and the rough patch between B and C
Question 2: Determine the speed of the block at point C

My attempts:
I'm really struggling determining the coefficient of friction. When that is determined I don't think I'll have any issues finding the speed of the block.

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...
