Question: A billiard ball initially at rest is given a sharp blow by a cue stick. The force is horizontal and is applied at a distance

A billiard ball initially at rest is given a sharp blow by a cue stick. The force is horizontal and is applied at a distance 2R/3 below the centerline, as shown in Figure. The initial speed of the ball is v₀, and the coefficient of kinetic friction is μ_k.

(a) What is the initial angular speed ω₀?

(b) What is the speed of the ball once it begins to roll without slipping?

(d) What is the frictional work done as it slides on the table?
