Ahockey puck is struck so that it slides at a constant speed and strikes the far side of the rink, 58.2 m away. the shooter hears the sound of the puck after 1.9 seconds. the speed of sound is 340 m/s.
how fast was the puck moving?

Explanation:

Let hockey puck is moving at constant speed v

so here we have

so time taken by the puck to strike the wall is given as

now time taken by sound to come back at the position of shooter is given as

so we know that total time is 1.9 s

now we have
