You are on a boat on the south side of a river that is flowing due east at 3 m/s. You are trying to reach a point across the river that is due north. Explain how you can adjust the direction of a boat so that it travels straight across the river. In order for this to happen what must the horizontal component of the boat velocity be? Are there any restrictions on the speed of the boat compared with the speed of the river? Explain.
In order to reach the opposite end of the river, you have to row your boat at a certain angle from horizontal such that net horizontal velocity becomes zero. Hori ... See the full answer
