A `10` kg ball `A` moving horizontally with a speed of `8` m/s collides with a `20` kg ball `B` initially at rest. After collision, the balls `A ` and `B` move along directions making angles of `30° ` and `45°` respectively with horizontal. Find the final speed of ball `B`.

A ball weighing 4 kg and moving with velocity of 8 m/sec. Collides with a stationary ball of mass 12 kg. After the collision, the two balls move together. The final velocity is

A ball moving with a speed of 9m//s strikes an identical ball at rest, such that after the collision, the direction of each ball makes an angle of 30^(@) with the original line of motion. Find the speeds of the two balls after collision.

A ball of mass 1 kg moving with a velocity of "0.4 ms"^(-1) collides with another stationary ball. After the collision, the first ball moves with a velocity of 0.3ms^(1) in a direction making an angle of 90^(@) with its initial direction. The momentum of the second ball after the collision will be (in kg ms^(-1) )

A billiard ball moving at a speed of 6.6 ms–1 strikes an identical stationary ball a glancingblow. After the collision, one ball is found to be moving at a speed of 3.3, ms–1 in a direction making an angle of 60º with the original line of motion. The velocity of the other ball is
