Achild kicks a stone along the sidewalk with a force of 520 newtons. the stone travels 1.5 meters in 0.30 seconds. how powerful is the child's kick?

2,600 w
1,700 w
47 w
1.5 w

2,600 W

Explanation:

The power can be expressed as the product between the force applied and the velocity of the object:

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:

So now we can use the first equation to find the power:
