    Solving for two unknowns in a 2-D elastic collision. HELP

    Hmm... I guess it can't be solved since there are two unknown variables unless I am forgetting something fairly obvious. (or maybe its too hard for all you physics masters :biggrin: ) Thanks anyway.

    Solving for two unknowns in a 2-D elastic collision. HELP

    I tried using the conservation of kinetic energy but it still leaves me with two unknowns on one side. since Ki=Kf Ki = (1/2 x M1 x VAi^2) + (1/2 x M1 x VBi^2) = (1/2 x M1 x VAf^2) + (1/2 x M1 x VBf^2) = Kf So if I plug in my values it solves the initial side but not the final side...

    Solving for two unknowns in a 2-D elastic collision. HELP

    Yes I did let me show you my work: X component: (M1 x VAi) + (M2 x VBi) = (M1 x VAf cos theta) + (M1 x VBf cos theta) Y component is the same except for cos is replaced by sin and negative VBf. So I got this for X component: (0.039 x 5.5) + (0.064 x 0) = (0.039 x VAf cos 65) +...

    Solving for two unknowns in a 2-D elastic collision. HELP

    Hey everyone. I am really stuck on a problem that seems simple but I just can't figure it out. The problem goes as follows. There is a collision between two pucks on an air-hockey table. Puck A has a mass of 0.039 kg and is moving along the x-axis with a velocity of +5.5 m/s. It makes a...
