Compute the all parts of given problem:
Problem: A 0.300 kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.900 m/s when it makes a head-on collision with a stationary 0.150 kg glider.
Part I: Find the magnitude of the final velocity of first glider if the collision is elastic.
Part II: Find the magnitude of the final velocity of second glider if the collision is elastic.
Please use great detail in explaining the solution. Thank you.
