Question

Note: Use principles of physics to solve the problem and then verify your answer using the simulation. Consider these four situations:
Case A: The boat speed is 4 m/s; the boat direction is 0 degrees; the river speed is 2 m/s.
Case B: The boat speed is 4 m/s; the boat direction is +30 degrees; the river speed is 2 m/s.
Case C: The boat speed is 4 m/s; the boat direction is -30 degrees; the river speed is 2 m/s.
Case D: The boat speed is 4 m/s; the boat direction is +15 degrees; the river speed is 2 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) Rank these cases by the distance traveled in crossing the river, from largest to smallest.

Explanation / Answer

a) B=C>D>A b) B>D>A>C
