problem

Consider a flat billiards table with a round spherical ball kept on it. The billiards table is a horizontal plane, represented by the Cartesian coordinate system as the plane `z=0z = 0` with the x and y axes lying in the plane of the table. The coefficient of kinetic friction between the ball and the table is `μ\mu`, the radius of the ball is `RR`, and the mass of the ball is `mm`, with the mass uniformly distributed. In this question, the ball is hit with a cue stick. Consider the collision between the cue stick and the ball: Assume the point of contact (at this moment) between the ball and the table is `PP`, the center of the ball is `CC`, and the point of impact (point where the stick hits the ball) is `TT`. Initially, the ball is at rest. It is assumed that after the collision, the ball remains in contact with the table and does not lift off: The collision is instantaneous. The impulse given is along the vector `TA\vec {TA}` where `AA` (not the same as `PP`) is any general point on the table Identify the direction of the velocity of the ball after the ball begins to roll purely. Give your answer in the form of `Px\vec{Px}` where the vector starts at point `PP` and ends at xx` which represents any one of the points mentioned above `(A,T,P,C) (A, T, P, C) `. Think step by step and solve the problem below. At the end of your response, write your final answer on a new line starting with “FINAL ANSWER”. It should be an answer to the question such as providing a number, mathematical expression, formula, or entity name, without any extra commentary or providing multiple answer attempts.

Original LaTeX notation
Consider a flat billiards table with a round spherical ball kept on it. The billiards table is a horizontal plane, represented by the Cartesian coordinate system as the plane  `\(z = 0\)` with the x and y axes lying in the plane of the table. The coefficient of kinetic friction between the ball and the table is  `\(\mu\)`, the radius of the ball is  `\(R\)`, and the mass of the ball is  `\(m\)`, with the mass uniformly distributed. In this question, the ball is hit with a cue stick.

Consider the collision between the cue stick and the ball: Assume the point of contact (at this moment) between the ball and the table is `\(P\)`, the center of the ball is  `\(C\)`, and the point of impact (point where the stick hits the ball) is  `\(T\)`. Initially, the ball is at rest. It is assumed that after the collision, the ball remains in contact with the table and does not lift off: The collision is instantaneous.

The impulse given is along the vector `\(\vec {TA}\)` where `\(A\)` (not the same as `\(P\)`) is any general point on the table

Identify the direction of the velocity of the ball after the ball begins to roll purely. Give your answer in the form of `\(\vec{Px}\)` where the vector starts at point `\(P\)` and ends at \(x\)` which represents any one of the points mentioned above `\( (A, T, P, C) \)`.
