Question

1. 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?

Answer 1

Correct me !

20,000 x 10 x cos(45) = 141421.4 J

So since 1 = 3600, p = W/t = 39.9 J/s ?

Answer 2

Sorry, I meant 2.00 x 10^4
