Topic: Hockey Icing Shortly after a faceoff in your defensive zone, you get the puck at your face-off dot (see rink diagram below) and attempt to clear the puck from your zone. You fire the puck at a speed of 25 m/s such that the puck slides flat on the ice, bounces off the boards right at your blue line, and continues toward the offensive zone (near the other team's net). The period has just begun and the ice is smooth, so you can assume the frozen puck never bounces on the ice or rolls (it does bounce off the boards though...). You are playing on an NHL-regulation ice surface. Model the motion of the puck, including the bounce off the wall, until the puck reaches the opposite goal line (the red line that is even with the other team's net). Provide a plot of the puck's path distance vs. time and velocity vs. time (i.e., the position and speed along the path it travels, not the x-y position relative to the rink). Do not neglect air resistance. Immediately as you release the puck from the face-off dot, one of your teammates is skating full- speed at your blue line to where the puck would cross the opponent's goal line. Determine the likelihood that your teammate can prevent icing (a standard NHL rule). DEFENDING ZONE NEUTRAL ZONE ATTACKINC ZONE 20 ft 20 ft Faceoff dot Initial puch direction DIRECTION OF PLAY
