A 0.415-kg hockey puck, moving east with a speed of 2.65 m/s, has a head-on collision with a 0.910-kg puck initially at rest.
Assuming a perfectly elastic collision, what will be the velocity of each object after the collision?
=======
The solution is:
v ' (lighter puck) , v' (heavier puck) = -0.990, 1.66 m/s, respectively.
My question is, wouldn't the lighter puck be expected to have a higher velocity magnitude than the heavier puck following the collision?
