(a) Calculate the approximate force on a square meter ofsail, given the horizontal velocity of the wind is 6.00 m/sparallel to its front surface and 3.50 m/s along its backsurface. Take the density of air to be 1.29 kg/m3 . (Thecalculation, based on Bernoulli’s principle, is approximate dueto the effects of turbulence.) (b) Discuss whether this force isgreat enough to be effective for propelling a sailboat.

(a) Calculate the approximate force on a square meter of
sail, given the horizontal velocity of the wind is 6.00 m/s
parallel to its front surface and 3.50 m/s along its back
surface. Take the density of air to be 1.29 kg/m3 . (The
calculation, based on Bernoulli’s principle, is approximate due
to the effects of turbulence.) (b) Discuss whether this force is
great enough to be effective for propelling a sailboat.
