Not to take away from the OP's questions but I'm on this question as we speak; If we use the conservation of momentum, wouldn't the two pucks final velocity be equal to zero at the closest point? Since like charges repel, would their closest point of contact not be when all the energy is in the...

Hey everyone! I'm new to these forums so I apologize in advance if I do something wrong! I just had a quick question about the momentum in one direction equation m_1v_1o +/- m_2v_2o = m_1v_1f +/- m_2v_2f; I'm just not sure when I'm supposed to add these values and when I'm...
