A bee and fly are flying at the same speed, and toward each other in a straight horizontal line. They have the same mass, and collide and stick together. Let’s ignore air resistance and wind.

What is their velocity 1 s after they collide? Assume that once they collide, they are in free-fall. Between the collision and this time, is momentum conserved? Why or why not? If not, what is the change in momentum?
