A glider of 0.150 kg is moving to the right (+x) on a frictionless, horizontal air track having a speed of 0.80m/s. It consists of an elastic collision having a 0.300 kg glider moving to the left (-x) with the speed of 2.20m/s.
i) Determine the initial momentum of each glider? Derive the momentum in terms of unit vectors.
ii) Determine the velocity (magnitude and direction) of each and every glider after the collision.
iii) Illustrate that kinetic energy which is conserved.
