A 0.15kg hockey puck slides directly North across the ice at a speed of 30m/s and hit the blade of a player's hockey stick. The blade exerts upon the puck a 12N force-directed East for a time of 0.5s.

1. What is the magnitude and direction of the puck's momentum before contact with the hockey-stick blade, where the direction angle is measured counter-clockwise from the East?

2. What is the magnitude and direction of the impulse delivered to the puck by the hockey-stick blade?

3. What is the magnitude and direction of the puck's momentum after contact with the hockey-stick blade?

4. What is the speed of the puck after contact with the hockey-stick blade?

5. Show how to geometrically subtract the hockey puck's initial momentum from its final momentum to determine the puck's change in momentum. Initial and final momentum vectors should have tick-marks to identify their relative lengths.
