OMGZ. you just taught me soooo much more than my own teacher.

@LILMattOwns Thanks for taking the time to let us know we helped. Best of luck with your course.

werent you supposed to use 7.2 m/s instead of 6 m/s? because if you use 6 m/s you only count the time that would take the person to swim straight across excluding the waters affection on the swimmer

[PhysicsEH]

@xxAlexLoves182xx Surprisingly, the velocity of the water does not effect the time it takes to cross because the velocity of the river has no component or part in the direction across the river. If the river flows faster, you end up further down stream but you are still crossing at 6m/s toward the other side so it still takes the same time. If you consider the velocity triangle and the displacement triangle as a pair, it simplifies the solution (see 3:35) I hope this helps.

i wish you were my real physics teacher....mine is from north india....and its just like listening to popcorn pop.....thanks...this helped a lot..:)

@PhysicsEH he got a 100 in the course.

i had the most trouble with air plane problems, yet i found 2-d elastic collisions easy..
