    Ball collision momentum problem

    That's exactly what I did...I imagined the situation at the moment of impact... There is a right triangle with hypotenuse 8 and opposite side 1...

    Ball collision momentum problem

    But I think that both energy and momentum are conserved in this situation... Or am I wrong?...

    Ball collision momentum problem

    They are sliding. And I have one standard equation (energy conservation) and one two dimensional vector equation (momentum conservation) so basically I have three equations and just two unknowns and therefore I'm not able to find a solution.

    Ball collision momentum problem

    Homework Statement Hello. I was solving this problem about two balls in a plane colliding elastically. The first one had mass 100g radius 5cm and started with velocity of 3m/s to the right and hit the second ball with mass 50g radius 3cm(initially stationary). It hit the second ball such...
