IB Physics Conservation of linear momentum

A tutorial sheet on linear momentum.

  1. State the law of conservation of linear momentum.
  2. In the collision of two particles the change in momentum of one particle is 2 Ns south-east. Find the change in momentum of the other particle.
  3. A ball of mass m falls from rest at a height h and bounces vertically to a height h/2. Find the momentum gained by the Earth in the collision.
