Sorry, I meant to type 72.0 in the original problem instead of 72.9. Can you explain to me what you mean by vector components? I know what they are, I am just confused as to how you can apply them to this problem.

Homework Statement Two boats, A and B, travel with a velocity of 4.90m/s across a river with a width of 72.9m. The river flows with a velocity of 2.50m/s. Boat A travels the shortest distance and boat B travels the shortest time. If both start at the same time, how much time will they take...

Yes, I was able to draw a diagram :) My problem though is calculating the coefficient of friction. I believe the radius was 12m and the rotational speed was approx. 8rad/s

Hey guys! Ok, so I don't have that much to work with, and I am sorry for my lack of detail, but my memory is a bit fuzzy. I had to do a problem like this for my physics test yesturday: On the test we were given a problem involving a roller coaster (Rotating Drum of Death was its name)...
