...and how do you convert revolutions per minute to this unit?

Homework Statement Okay, so we've got a solid cylinder attached to a horizontal massless spring that rolls without slipping along a horizontal surface. The system is released from rest with the spring stretched past the equilibrium point. (The first two parts of this problem ask for...

Thank you very much!

Ah yes, that's a problem! I must use the radius for the bullet part of the total inertia. So the rotational inertia should be (1/12)M_R*L^2+M_B*(L/2)^2 But why is it still the wrong answer? If that's the only error, I must be making a computation mistake. And about the tag error, I don't know...

The 'i's, 'j's, and 'k's with the little hats on top of them (my teacher calls them "i-hat" and "j-hat" and "k-hat") represent components. i=x component, j=y component, k=z component. So vector 'A' has an x component of positive 6 and a y component of positive 2. Now, all vectors have a...

Alright, this is my first experiment with this forum. Hopefully, I do this right! Homework Statement I'm going to give the problem in terms of variables, not the numbers I'm given, so that people can't give me a direct answer. A uniform thin rod of length (L)m and mass (M_R)kg can rotate...
