In international play hockey puck is struck by a "green team" hockey player at the blue line with 2:35 on the clock. It is stopped by an "orange team" player at the opposite blue line with 2:32 on the clock. On an international hockey rink the blue lines are 17⅔ m apart. Calculate the speed of the hockey puck.

To determine the speed of the hockey puck, we first need to understand the distance it traveled and the time it took to do so.

  1. Distance Traveled: The puck was struck at one blue line and stopped at the opposite blue line. The distance between the two blue lines is 17⅔ meters.

  2. Time Taken: The puck was struck at 2:35 on the clock and stopped at 2:32. The difference in time is:

    • 2:35 to 2:34 is 1 second.
    • 2:34 to 2:33 is another second.
    • 2:33 to 2:32 is another second. Thus, the total time taken for the puck to travel is 3 seconds.
  3. Calculating Speed: The speed can be calculated using the formula: \[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \] Plugging in the values: \[ \text{Speed} = \frac{17.67 \text{ m}}{3 \text{ s}} \approx 5.89 \text{ m/s} \]

So to conclude:

  • The distance traveled by the hockey puck is 17⅔ m.
  • The time taken for the puck to travel that distance is 3 seconds.
  • The calculated speed of the hockey puck is approximately 5.89 m/s.

The correct response regarding the distance traveled is: 17⅔ m is the distance traveled.
