Solve the all parts of following problem:
Problem: A 0.400kg glider is moving to the right on a frictionless, ¬horizontal air track with a speed of 0.900m/s when it makes a head-on collision with a stationary 0.150kg glider.
Part A: Find the magnitude of the final velocity of first glider if the collision is elastic?
Part B: Find the magnitude of the final velocity of second glider if the collision is elastic.
Part C: Find the final kinetic energy of first glider.
Part D: Find the final kinetic energy of second glider.
I need help to find the magnitude of the final velocity of second glider if the collision is elastic.
