A rod of mass "M" and length "l" is kept at rest on a smooth horizontal surface. Aparticle of mass "m" and moving with speed "u" collides elastically with one end of the rod and becomes stationary after collision.Find

  • Velocity of centre of mass of rod after collision
  • Angular momentum of rod after collision
  • Ratio of "m" to "M"

[In case you are using the method of conservation of Angular momentum, Kinetic Energy, and Linear Momentum , please specify that how will they be constant ?
