(a) Assuming that F and v have the same magnitudes for each sailboat, will the propulsion power delivered to sailboats B be greater than, less than, or the same as the propulsion power delivered to sailboats C? Explain.
(b) If F = 870 N and v = 11 m/s, what propulsion power is delivered to sailboats B, for which θ = 79°?
(c) What propulsion power is delivered to sailboats C, for which θ = 56°? |
