Physics to solve the problem and then verify your answer using the simulation. Consider these four situations: Case A: The boat speed is 8 m/s; the boat direction is 0 degrees; the river speed is 4 m/s. Case B: The boat speed is 8 m/s; the boat direction is +30 degrees; the river speed is 4 m/s. Case C: The boat speed is 8 m/s; the boat direction is -30 degrees; the river speed is 4 m/s. Case D: The boat speed is 8 m/s; the boat direction is +15 degrees; the river speed is 4 m/s. (a) Rank these cases by the time it takes to cross the river, from largest to smallest. Use only > and/or = signs in your ranking (e. g., B>A>C=D). B=C>D>A Correct: Your answer is correct. (b) Rank these cases by the distance traveled in crossing the river, from largest to smallest. B=C>D>A Incorrect: Your answer is incorrect.
