Answer:
2,600 W
Explanation:
The power can be expressed as the product between the force applied and the velocity of the object:
[tex]P=Fv[/tex]
where F is the force applied and v is the velocity.
We already know the force, F=520 N, while we can find the velocity of the stone by dividing the distance covered by the time taken:
[tex]v=\frac{d}{t}=\frac{1.5 m}{0.3 s}=5 m/s[/tex]
So now we can use the first equation to find the power:
[tex]P=(520 N)(5 m/s)=2600 W[/tex]
