A river flows at a speed of 4.6m/s. A boat, capable of moving with a speed of 5.8 m's in still water is rowed across the river at an angle of 53 degrees to the river flow. Calculate the resultant velocity with which the boat moves and the angle that its resultant motion makes to the river flow.
In other words, HELP! Can you show me the work- this question was from a quiz we took last week and I got it wrong, my teacher sucks and didn't explain it AT ALL!
