Homework Statement
Two air hocky pucks collide head-on elastically on a frictionless surface. The smaller puck has a mass of 0.050 kg and is moving to the right at 5.0 m/s while the larger puck has a mass of 0.10 kg and is moving to the left with a speed of 2.0 m/s. Find the velocity of each after the collision.
Homework Equations
M1V1+M2V2=M1V'1+M2V'2
.5M1V1^2+.5M2V2^2=.5M1V'1^2+.5M2V'2^2
The Attempt at a Solution
I am pretty sure I must derive an equation from conservation of momentum and conservation of energy.
