Not true what you said
Your statement
(C) Striking a tennis ball at a spot other than the center of percussion can result in a jarring feeling.
The statement above implies that only it is only the "center of percussion" that prevents vibrations.
The passage does not mention that ONLY if you hit the sweet spot - center of percussion you do not have vibrations AT ALL, and in other spots YEs or maybe.
relatively smooth means that even at the center of percussion you can experience some sort of vibration and it is also true the other way around: in other spots, you can have NO vibrations or just a few and have some sort of comfort hitting the tennis ball
C is the correct answer

When the player strikes the ball at the center of percussion, her wrist is jerked neither forward nor backward, and she experiences a [u]relatively smooth[u], comfortable tennis stroke.

Hi Carcass,
Thanks for your post. I apologize, I'm not sure I fully understand what you wrote. The quote in my previous post is the quote from the correct answer choice, it wasn't my statement.
quote from passage,
This "no net force" = no jarring feeling is what I inferred.
Additionally this section says, center of percussion is a second sweet spot
Thus from what I gather, the actual answer - Choice C (question 5) doesn't exactly fit into this sentence, because it says "other than the center of percussion" that implies this is the only spot one on the racket.
quote from answer choice,
Now if this answer was reworded as follows, I would have definitely picked C.
Striking a tennis ball at a spot other than the sweet spot and center of percussion can result in a jarring feeling.
Thank you again for posting detailed replies, I truly appreciate the effort you are putting into this forum !

quote from passage,
Quote:
The reason for this lack of motion is that the force on the upper part of the hand would be equal and opposite to the force on the lower part of the hand, resulting in no net force on the tennis players’ hand or forearm. The center of percussion constitutes a second sweet spot because a tennis player's wrist typically is placed next to the end of the racket's handle.

The red is C and the blue is your statement
This is NOT totally true In the center of percussion we do NOT have vibrations AT ALL and the other area YES
NO
We can have also vibrations in the center where we do have a tiny amount of them and we do have a lot of them on the rest but could we also do not have
Moreover C says
(C) Striking a tennis ball at a spot other than the center of percussion can result in a jarring feeling."
Can imply is NOT 100% sure
Hope this helps
