So, we're playing snooker.... 1. The problem statement, all variables and given/known data A (uniform) snooker ball of radius r, at rest on a table, is struck by a cue at a point a distance h above the table. Assume the cue tip is travelling horizontally, in a plane through the centre of the ball. As a result, the ball begins to move with an initial linear speed V0 and angular speed w0. Consider the cue as acting with a large force F for a short time. Ignoring the effects of friction between the ball and the table for this time, find an expression for the ratio V0/w0 in terms of h. 2. Relevant equations Once I've sussed the question, I can identify which. 3. The attempt at a solution Well, I'm confused due to the sentence; "Assume the cue tip is travelling horizontally, in a plane through the centre of the ball". This to me means, that h = r? Therefore, if friction is to be ignored this time, the ball will not (initially) rotate? If someone could clear this up, I'm sure I can crack on with the next few parts of the question.
