A 166 gram hockey puck has a initial velocity of vx = 27 m/sec and vy = 16 m/sec. It rickochets of the boards and has a final velocity of vx = -27 m/sec and vy = 16. The collision bewteen the puck and the boards takes 0.0159 seconds.
1) What is the impulse delivered to the hockey puck in the x direction?
2) What is the average force on the hockey puck in the x direction during the collision?
