Show that in order to get a billiard ball to roll without sliding from the start the cue must hit the ball not at the center (that is, a height above the table equal to the ball's radius R) but exactly at a height 2/5 R above the center [Hint, Consider linear momentum and angular motion of the ball. Apply the condtion for rolling without sliding. F = ma and tau = F xx h = 2/5mR^(2)xx alpha . Condition rolling without a sliding it a =alphaR]

In order to get a billiard ball to roll without sliding from the start, where should the cue hit ? Calculate the height from centre of the sphere. Take R as the radius of sphere.

The cue stick hits a cue ball horizontally a distance x above the centre of the ball. Find the value of x for which the cue ball will instantaneously roll without slipping. Calculate the answer in terms of the radius R of the ball.

A solid uniform sphere of mass m is released from rest from the rim of a hemispherical cup so that it rolls without sliding along the surface. If the rim of the hemisphere is kept horizotnal, find the normal force exerted by the cup on the ball when the ball reaches the bottom of the cup.

A spherical rigid ball is realeased from rest and starts rolling down an inclined plane from height h=7m, as shown in the figure. It hits a block at rest on the horizontal plane (assme elastic collision). If the mass of both the ball and the block is m and the ball is rolling without sliding, then the speed of the block after collision is close to

A uniform ball of radius r rolls without slipping down from the top of a sphere of radius R Find the angular velocity of the ball at the moment it breaks off the sphere. The initial velocity of the ball is negligible.

In the game of billiards, all the balls have approximately the same mass, about 0.17 kg. In the figure, the cue ball strikes another ball such that it follows the path shown. The other ball has a speed of 1.5 m/s immediately after the collision. What is the speed of the cue ball after the collision?
