Homework Statement
(1) A River flows due east at 1.20 m/s. A boat crosses the river from the south shore to the north shore by maintaining a constant velocity of 9.0 m/s due north relative to the water. I got the velocity of the boat relative to shore at 9.08 m/s at 82.406 degrees north of east. What about if the river is 380m wide, how far downstream has the boat moved by the time it reaches the north shore?
Homework Equations
The Attempt at a Solution
I got the velocity by setting up components and using the Pythagorean theorem and tangent. What do I do with the 380m to figure out how far downstream the boat has moved by the time it reaches north shore? thanks
