On a frictionless air track, a 0.165 kg glider moving at 1.50 m/s to the right collides with and sticks to a stationary 0.265 kg glider.

What is the net momentum of this two-glider system before the collision? Use coordinates where +x is in the direction of the initial motion of the lighter glider (Express answer in kg•m/s)

What must be the net momentum of this system after the collision (Express answer in kg•m/s)

Use your answers in Parts A and B to find the speed of the gliders after the collision (Express in m/s)

Is the kinetic energy conserved during the collision?
