a) Describe the difference between local, advective, and total accelerations. You may use examples if you think it would be helpful. b) Use normal-curvature Bernoulli to explain how a thin canvas sail is able to generate lift. c) Write out the integral conservation of mass equation and clearly explain the conditions under which the terms in the integrand may or may not be taken out of the integrals and/or derivative. d) Cargo ships will frequently shoot water cannons at pirate vessels in order to defend themselves. Explain the relationship between the water jet velocity in 3 different frames of reference: that of the cargo vessel; that of the pirate ship; that of an observer on the shore.
