We considered this in an earlier tutorial looking at two hockey pucks colliding on ice. Let's say hockey puck A has 10 kg m/s of momentum before the collision, hockey

puck B has 0 momentum because it is at rest. After the collision, hockey puck A has 4 kg m/s of momentum. Hockey puck B would have to have 6 kg m/s. What was the total momentum before the collision? What was the total momentum after the collision? What was the impulse of hockey puck A? What was the impulse of hockey puc k B?
