RWP You ride in a boat whose speed relative to the water is 6.1 m/s. The boat points at an angle of 25° upstream on a river flowing at 1.4 m/s. (a) What is the velocity of the boat relative to the ground? (b) Suppose the speed of the boat relative to the water remains the same, but the direction in which it points is changed. What angle is required for the boat to go straight across the river-that is, for the boat to move perpendicular to the shores of the river?
