Finding kinetic coefficient of friction (pulley involved)

AI Thread Summary
To find the coefficient of kinetic friction for a wooden block on a dynamics track attached to a counterweight via a frictionless pulley, the system's mass and velocity after traveling a certain distance are crucial. The block has a mass of 0.1305 kg, while the counterweight is 0.050 kg, and the block reaches a velocity of 0.5767 m/s after moving 0.8 meters. The calculations involve applying Newton's second law and the work-energy principle to determine the forces acting on the system. The user is seeking assistance in completing these calculations to find the kinetic friction coefficient. The discussion highlights the need for clarity in applying physics equations to solve the problem effectively.

Homework Statement



A wooden block with mass 0.1305kg is sitting on a horizontal dynamics track. The block is attached to a counterweight of mass 0.050kg by means of a frictionless pulley (the counterweight is hanging off of the table). The system is released from rest, and after traveling 0.8 meters, the velocity of the block is 0.5767 m/s. Calculate the coefficient of kinetic friction

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...
