Okay, so my homework question is: 5) An object makes an elastic head-on collision with another "target" object which is initially at rest. If the ratio of incident mass over target mass is 0.5333, what is the velocity of the incident object after the collision in multiples of its incident velocity? Give the result with the appropriate sign taking the incident velocity as positive. Would any of ya'll be kind enough to help me solve this problem?! Thanks a bunches.
