Question

in a hockey rink, the two goal lines are 54 meters apart. a hockey puck slid from the center line directly to the goal line, which is half the distance from one goal line to the other. the puck slid that distance in 3 seconds. what was its velocity? write your answer as a whole number. meters per second directly toward the goal line

Explanation:

Step1: Calculate the distance

The distance between the two goal lines is \(54\) meters. The puck slides from the center line (half - way between the two goal lines) to the goal line. So the distance \(d=\frac{54}{2}=27\) meters.

Step2: Use the velocity formula

The formula for velocity \(v = \frac{d}{t}\), where \(d\) is the distance and \(t\) is the time. Given \(d = 27\) meters and \(t=3\) seconds. Then \(v=\frac{27}{3}=9\) meters per second.

Answer:

\(9\)
