A mass travels in a straight line with velocity vo perpendicular to a uniform stick of mass m and length L which is intially at rest The distance from the centre of the stick to the path of the travelling mass is h see figure Now the travelling mass m collides elastically with the stick and the centre of the sitck and mass m are observed to move with equal speed v after the collision Assuming that the travelling mass m can be treated as a point mass it follows that the distance h must be Then find the value vn of n m h m L
