The energy E (in foot-pounds) in each square foot of an ocean wave is given by the model E = 0.0029s⁴, where s is the wind speed (in knots). A graph of the model is shown. Estimate the wind speed needed to generate a wave that has 1000 foot-pounds of energy in each square foot.

 

A. 12 knots 

B. 24 knots 

C. 2900 knots 

D. 86,000 knots
