    What Happens to Puck Speeds After an Inelastic Collision with Energy Loss?

    First, introduce suitable variables. For example, let p_b, p_g, m_b, m_g be the momenta and masses of the two particles. You will need others. Your claim "green puck = m; blue puck = 1.30m" is physically meaningless. What PROPERTY of the pucks are you assigning those values? Can you...
