On a frictionless air track, a 0.150 kg glider moving at 1.20 m/s to the right collides with and sticks to a stationary 0.250kg glider. (a) What is the net momentum of this two glider system before the collison?
(b) What must be the net momentum of this system after the collision? Why?
(c) Use your answers in parts (a) and (b) to find the speed of the gliders after the collision.
(d) Is kinectic energy conserved during the collision?
