Question

A sailboat moves north for a distance of 10.00 km when blown by a wind from the exact southeast with a force of 5.00 × 104 N. How much work was done by the wind the answer is 3.54 × 108 J I need a brief explanation of this

Answer 1

Work = (force)(distance) (cos angle between them)

Answer 2

W = (5 x 10^4 N) (10^4m) [cos (45)] = 3.54 x 10^8 N-m or J

Answer 3

thank you
