1. The problem statement, all variables and given/known data A ball with mass 2.5 kg is moving in outer space with a velocity of 6.0 m/s horizontally, and a box of mass 4.5 kg is moving with a velocity of 4.0 m/s at a angle of 120 degrees from the horizontal. the two collide and stick together. Find the final velocity of the pair. 2. Relevant equations Px = Pix = Pfx MaVa + MbVb = Vf(Ma+Mb) 3. The attempt at a solution My first question is whether or not, we take into account the angular velocity of the ball. With that said, I started off the solution using the above formula for x and y. In the X: MaVax + MbVbx = Vf(Ma+Mb) with Vbx = 4 cos 120, this came out to .85ms-1, is this correct?
