But of course tennis players are also interested in applying power, and spin.

To go a little deeper if I may.
For ATP forehand 3 (see the classification of Yandell et al) the vertical component of the racket head speed has to go from 0 to 20 mph in 11 milliseconds.
It is NOT a piece of cake to achieve it.Some shanks are generated.
The banner example is reasonably skilled Fderer who shanks A LOT during some matches.
On the other hand it need not be extreme. I am talking about acceleration, not maximum possible acceleration at all costs.

I think that the impact of the ball slowing the racket needs to be taken into consideration. I would guess it is more or less impossible to not have the ball deccelerate the racket at impact. The question is more, does the player also do it.

Which is why spin is important. It is both about applying spin and speed in the right combination. If you were talking about the subject at hand, I am not sure.

Well I do not mind a few golf analogies in the thread. I guess everbody knows there are differences, but it is all good with me.
