So after looking at a great deal of confusing information online, I have come to these conclusion for a solid and hollow sphere. 1. Both the solid sphere and hollow sphere, when hit with the same impulse force will have the same starting linear velocity and rotational velocity. 2. During...

And you have convinced me that I need to consider slipping.

This is beyond the level of questions asked in his homework. And he has moved on, but it's nagging me. I guess I will have to go in the attic and dig out my old engineering books.

You said "If balls of the same mass are rolling at the same speed with the same rolling resistance." I would assume in the situation you presented the balls would travel the same distance. But that does not intuitively seem correct in real life. It would seem to me, they would not roll at...

No it is not homework. Just a question my son asked (who is currently taking physics) that I (having not taken an engineering class in 20 years) felt I should be able to answer, but I can't and its driving me nuts.

I am stuck on problem presented about putting golf balls. A stationary golf ball (mass=45g, dia=42mm, solid & homogeneous) is struck by a horizontal force (putter) and ignoring sliding immediately starts rolling on a level putting green. The ball eventually stops due to rolling resistance...
