The work done by the stick on the hockey puck is equal to the magnitude of the force times the distance covered by the puck:
[tex]W=Fd=(750 N)(2.0 m)=1500 J[/tex]
And the power of the stick is equal to the ratio between the work done and the time taken, therefore
[tex]P= \frac{W}{t}= \frac{1500 J}{0.30 s}=5000 W [/tex]
