    What is the final speed of a mass collision?

    No, I think you've lost me guys, I'm not sure I'm getting what y'all mean about m2 = 5*m1. what about the initial velocity that we don't have? Cause when i substitute m2 I still can't get Vf.

    What is the final speed of a mass collision?

    m1Vi1 + m2Vi2 = m1Vf2 + m2Vf2 Vf = Vi(m1-m2) / (m1+m2) this is how i interpreted it, I'm not sure if I'm on the right track or not.
