Hockey puck A with mass 156 grams gliding at 3.55 m/s on ice (frictionless) overtakes and impacts another, slower hokey puck B from behind sliding in the same direction at 1.45 m/s. after the impact, puck A slows to 2.15 m/s in the same direction while puck
B (hit from behind) begins gliding at 2.55 m/s in the same direction. (elastic collision occurred)
Is the mass of hockey puck B identical to A?
If not, what is it?
What is the kinetic energy of puck A before the collision? After?
