A ball of mass 100g moving at a speed of 12 m `s^(-1)` strikes another ball of mass 200 g at rest. After the collision both the balls move with a common velocity. Find the common velocity.

A ball of mass 100g moving at a speed of 12 m s^(-1) strikes another ball of mass 200 g at rest. After the collision both the balls stick to each other and move with a common velocity. Find the common velocity.

A ball of mass 10 kg is moving with a velocity of 10 m / s . It strikes another ball of mass 5 kg which is moving in the same direction with a velocity of 4 m / s . If the collision is elastic, their velocities after the collision will be, respectively

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 of mass 100 g is moving with a velocity of 100 msec^(-1) . Find its wavelength.

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 10" m s"^(-1) strikes an identical ball such that after the collision the direction of each ball makes an angle 45^(@) with the original line of motion. Find the speeds of the two balls after the collision.
