A billiard ball that is initially at rest is given a sharp blow by a cue stick
A billiard ball that is initially at rest is given a sharp blow by a cue stick. The force is horizontal and is applied at a distance h = 2R/3 below the centerline, The speed of the ball just after the blow is v0 and the coefficient of kinetic friction between the ball and the billiard table is μk find angular velocity just after blow, velocity once roles without slipping, and KE just after hit.

If a billiard ball is hit in just the right way by a cue stick,
the ball will roll without slipping immediately after losing
contact with the stick. Consider a billiard ball (radius
r, mass M) at rest on a horizontal pool table. A
cue stick exerts a constant horizontal force F on the ball
for a time t at a point that is a height h above
the table's surface (see the figure).(Figure 1) Assume that the
coefficient of...

On a billiards table a cue ball is initially at rest at the point O on the table. It is struck by the stick so that it leaves the stick with a center of mass speed vo and reverse spin of angular speed oo. A kinetic friction force acts on the ball as it skids initially across the table. o da e a) Explain why the ball's angular momentum is conserved about the point。. b) Using the conservation of the...
A cue ball of mass m1 = 0.375 kg is shot at another billiard ball, with mass m2 = 0.53 kg, which is at rest. The cue ball has an initial speed of v = 5.5 m/s in the positive direction.
A cue ball of mass m1 = 0.375 kg is shot at another billiard ball, with mass m2 = 0.53 kg, which is at rest. The cue ball has an initial speed of v = 5.5 m/s in the positive direction. Assume that the collision is elastic and exactly head-on.Part (a) Write an expression for the horizontal component of the billiard ball's velocity, v2f, after the collision, in terms of the other variables of the problem. Part (b) What is this velocity, in meters per second? Part (c) Write an expression for...
