A sailboat moves north for a distance of 10.00 km when blown by a wind from the exact southeast with a force of 2.00 * 104 N. The sailboat travels the distance in 1.0 h. How much work was done by the wind? What was the wind's power? Your response should include all of your work and a free-body diagram.

The work done to move the sailboat is calculated through the equation below,

W = F x d

where F is force and d is the distance.

Substituting the known values from the given above,

W = (2.00 x 10⁴ N) (10 km) (1000 m / 1km)

= 2.00 x 10⁸ J

Thus, the work done is 2.00 x 10⁸J.
