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?

A projectile is shot at a hill, the base of which is 300 m away. The projectile is shot at 60degrees above the horizontal with an initial speed of 75 m/s. The hill can be approximated by a plane sloped at 20degrees to the horizontal. Relative to the coordinate system shown in the following figure, the equation of this straight line is y=(tan 20o)x-109. Where on the hill does the projectile land?
