Ok thanks for your help it was much appreciated.

Ok so: v0 = 3/2*vR vR = 2/3*v0 But I don't think I can go on any further because I haven't actually been given any values for μk, v0 or R So the closest I can come is: t = v0/(3*μkg) t = v0/(29.4*μk)

So that would make something like: Δp = Mv0 - MvR = -fkt and Δp = Icmω = fkRt so vR = v0 - μkgt and ω = (2μkgt)/R so vR = 2μkgt = v0 - μkgt v0 = 3μkgt I always seem to have too any unknowns left over

Homework Statement A solid homogeneous cylinder of mass M and radius R is moving on a surface with a coefficient of kinetic friction μk. At t=0 the motion f the cylinder is purely translational with a velocity v0 that is parallel to the surface and perpendicular to the central axis of the...

Thanks for the welcome. I was trying to understand it in terms of kinetic energy and work done by the friction as it rolls. Using the forces on the cylinder instead makes more sense. Also, a slightly related question. Would the vcm of a rolling cylinder with slipping be the same as the...

If I push a cylinder along a surface with friction then am I right in saying that it would almost instantly start a pure rolling motion with a combination of translational and rotational kinetic energy? Or would it start initially with pure translational motion and gradually accelerate...
