b) To slow the boat very quickly a thrust reverser (or speed brake) is deployed (as shown in the figure). What force does the engine/thrust reverser combination exert on the boat if the engine is operating in the same condition as in part a? That is, consider that the same water velocity is entering at station 1 and exiting at station 2 as in part a). The angle = 90°. Hint: Bernoulli's equation should hold for the flow outside the engine, i.e., between stations 2 and 3.

Question
b) To slow the boat very quickly a thrust reverser (or speed brake) is deployed (as shown in the figure).
What force does the engine/thrust reverser combination exert on the boat if the engine is operating
in the same condition as in part a? That is, consider that the same water velocity is entering at
station 1 and exiting at station 2 as in part a). The angle = 90°. Hint: Bernoulli's equation
should hold for the flow outside the engine, i.e., between stations 2 and 3.
