Ball A of mass m, after sliding from an inclined plane, strikes elastically another ball B of same mass at rest. Find the minimum heihgt h so that ball B just completes the circular motion of the surface at C. (All surfaces are smooth).

A ball of mass m_(1) moving with a certain speed collides elastically with another ball of mass m_(2) kept at rest . If the first ball starts moving in reversed direction after the impact then

A ball of mass 4 kg moving on a smooth horizontal surface makes an elastic collision with another ball of mass m at rest in the line of motion of first ball. If after collision first ball moves in the same direction with one fourth of its velocity before collision, then mass of second ball is

A ball of mass 4 kg moving on a smooth horizontal surface makes an elastic collision with another ball of mass m at rest in the line of motion of first ball. If after collision first ball moves in the same direction with one fourth of its velocity before collision, then mass of second ball is

A ball of mass m moving with a velocity v undergoes an oblique elastic collision with another ball of the same mass m but at rest. After the collision if the two balls move with the same speeds , the angle between their directions of motion will be:

A ball is dropped from a height h on a inclined plane, ball collides elastically with the first plane. Find the value of 'h' (in meter) so that it strikes perpendicular on the second inclined plane.

A ball A moving with a certain velocity collides, with another ball B of the same mass at rest. If the coefficient of restitution is e, the ratio of the velocities of A and B just after the collision is
