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 glider of 0.300 kg moving to the left (-x ) with a speed of 2.20m/s.
i) Determine the initial momentum of each glider? Deduce the momentum in terms of unit vectors.
ii) Determine the velocity (magnitude and direction) of each glider subsequent to the collision.
iii) Represent that kinetic energy is conserved.
