So THIS is why people are afraid of clowns....

I know, the Clown Problem, right?  I think it is the trickiest problem of the set.  Two clowns shot out of a cannon and collide in mid-air?  What?  What kind of circus is this?

Fortunately, we only have to calculate the kinematics; we can leave calculations of the psychological trauma to others.

I have some hints for the clown problem, in case you get stuck.  Actually, it's more like a mostly-solved solution.  Your answers will vary because your problem will have different starting values, but hopefully it will be a good head start.
