A gas molecule having a speed of 322 m/s collides elastically with another molecule of the same mass, which is initially at rest. After the collision the first molecule moves at an angle of 30 degrees to its initial direction. Find the speed of each molecule after collision and the angle made with the incident direction by the recoiling target molecule.
