Work done = (force) x (distance)
Work done = (9 Newtons) x (10 meters) = 90 Joules
Power = (work done) / (time to do the work)
Power = (90 Joules) / (3 seconds)
Power = 30 watts
The wind has a lot more power than that. The ball robbed 30 watts from the wind.
If the ball had a different shape, or had smoother or rougher skin, or were lighter or heavier, it might have robbed more power from the same wind.
This it the kind of problem engineers have to solve in order to build a windmill that can extract the most power from the wind.
