On a frictionless, horizontal air table, puck A (with mass 0.245 kg) is moving toward puck B (with mass 0.360 kg), that is initially at rest. After the collision, puck A has a velocity of 0.115 m/s to the left, and puck B has velocity 0.660 m/s to the right.(adsbygoogle = window.adsbygoogle || []).push({});

Calculate the change in the total kinetic energy of the system that occurs during the collision.

I tried putting it all in to the change of kinetic energy equation but it does not work, this is my equation

.5(.245 kg)(-.155^2)+ .5(.36)(.66^2)= .08 J

But that answer is wrong, can smeone help?
