A boy is trying to cross a river 200m wide. He travels at 3m/s [N; relative to the water, but the water current has a velocity of 1m/s[E305]. 1) Find the boys velocity relative to the ground 2) The time it takes to cross the river 3) The direction he should orient himself so he would land exactly north of his starting point 4) How long would it take to cross river in #3? 5) Discuss why the times are different and why one is longer than the other
