A 0.15 kg hockey puck moving east at 8.0 m/s collides with a stationary 0.20 kg puck. After collision, the first puck moves at 4.0 m/s at 35° north of east. (a) Determine the velocity components of the second puck after collision. (b) Determine its magnitude and direction. (c) Explain why momentum must be conserved separately in the x and y directions.
