On a frictionless air track, a 0.140 kg glider moving at 1.35 m/s to the right collides with and sticks to a stationary 0.245 kg glider.
Part A: What is the net momentum of this two-glider system before the collision?
p=_______kg*m/s
Part B: What must be the net momentum of this system after the collision?
p=_______kg*m/s
Part C: Use your answers in Parts A and B to find the speed of the gliders after the collision.
v=_______m/s
Part D: Is kinetic energy conserved during the collision?
a. yes
b. no
