Question

The water in Conception Bay is moving 90º South of East(ie. South) at 2.8 km/h. The ferry making the crossing to Bell Island is heading 0º North of East(ie. east) at a speed of 24.8 km/h. Using a coordinate system where East is positive x and North is positive y, find the velocity of the boat relative to the ground. --------x and -------y

What is the magnitude of the velocity of the boat relative to the ground?
What is the angle the velocity vector makes relative to East-------
What is the speed of the boat relative to the ground?----------------
