Mass being dropped on spinning disk problem NEED HELP

AI Thread Summary
A disk with a radius of 1.25m and a mass of 10kg is spinning at 10 rad/s when a 5kg mass is dropped onto it at a distance of 0.50m from the center. The problem involves calculating the time and distance the mass slips on the disk, given a coefficient of kinetic friction of 0.40. Participants are encouraged to share their attempts and specific points of confusion to facilitate assistance. The discussion emphasizes the importance of showing work to receive effective help. Engaging with the community can lead to a clearer understanding of the physics involved.

Mass being dropped on spinning disk problem NEED HELP!

1. A disk has a radius of 1.25m and a mass of 10kg. It lies flat on a smooth table and is spinning with an initial velocity of 10 rad/s about a pin at its center. A 5kg mass is dropped on it at a distance of 0.50m from its center. Find:
(Extra credit) if the coefficient of kinetic friction between the block and the disk is 0.40, determine:
i. the time while slipping























ii. the distance traveled while slipping

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...
