If a baseball in flight strikes an house fly with a mass of 7g causing the fly to smash into the ball, what is the combined velocity of the ball and the fly after the collision?
----
If the baseball in flight strikes a super house fly with a mass of 4 kg causing the baseball to suddenly stop, while propelling the super fly forward, what is the resultant velocity of the super house fly after the collision?

For the second one I can tell you that the momentum has to be maintained (B=m*v)
so as B1=B2 (where B1 is the momentum before the clash, and B2 after the clash)
therefore m1*v1=m2*v2
- m1 - mass of the baseball
- v1 - speed of the baseball (before the clash)
- m2 - mass of the fly
- v2 speed of the fly (after the clash)
and from that, you get:
v2=(m1*v1)/m2
basic clashes... well, a bit advanced 2-dimensional clashes, since you gotta count the gravity as a constant force in the calculation, which I... do... not... know...
but my diploma says I do! :D ---> the power of modern education system!
