I need help with this problem, pleaseeeee?

A 0.142 kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.740m/s . It has a head-on collision with a 0.310 kg glider that is moving to the left with a speed of 2.29m/s . Suppose the collision is elastic. A) Find the magnitude of the final velocity of the 0.142kg ... show more A 0.142 kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.740m/s .
