(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A 2.00 kg mas (A) moving at 2.00 m/s strikes another 2.00 kg mass(B) which is at rest. Both are confined to a a straight line to move along.

An impossible outcome for this collision is that A sticks to B and they both move off together at 1.414 m/s. First show that this collision would satify conservation of kinetic energy and then explainwhy this is impossible.

2. Relevant equations

.5(m_{A})(v_{Ai})^{2}+.5(m_{b})(v_{bi})^{2}=.5(m_{A})(v_{Af})^{2}+.5(m_{b})(v_{bf})^{2}

3. The attempt at a solution

I get that this is a perfectly ineleastic collision but why is it impossible and what does the question mean by "show that this satifies the consevation of kinetic energy" Does the above question even relate to the equation for the consevation of kinetic energy?

ANy help is appreciated thanks!!!
