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 centreline of the ball. The initial speed of the ball is v0 and the coefficient of kinetic friction is Mu k. a) what is the initial angular speed w0? B) What is the speed of the ball once it begins to roll without slipping? C) What is the initial kinetic energy of the ball? D) What is the frictional work done as it slides on the table? a) w = w0 + alpha*t b) v = v0 + a*t c) K = 1/2mv^2 or 1/2(Iw^2)? d) may you help me with this one pls? I really find this one hard!
