Calculating Angular Velocity of a Rolling Sphere on an Inclined Plane

AI Thread Summary
To calculate the angular velocity of a solid sphere rolling down an inclined plane, the translational velocity must first be determined. The correct formula for translational velocity is v = d/t, where d is the distance traveled and t is the time taken. The initial calculations yielding 61 rad/s are considered too high by peers, who suggest results should be under 1 rad/s. It's essential to ensure accurate measurements of distance and time to achieve a correct angular velocity. Clarifying these values will lead to a more precise calculation.

Homework Statement



so i need to find the angular velocity of a solid sphere rolling down an inclined plane. I know the mass, radius, and distance the sphere travels.

Homework Equations





The Attempt at a Solution



I know how to get angular velocity, but i need the translational velocity first (m/s). Do i use d=v/t or d=1/2(Vi-Vf)(t) which should go down to v=2d/t. I am getting like 61rad/s and after talking to some other people, they said that was too big. They are getting theirs to be under 1...which doesn't make sense to me
 
Physics news on Phys.org
and i know the time it takes. And i meant to say v=d/t above
 
i need this tonight
any help would be great!
thanks
 

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...
