Relative Velocity in Two Dimensions
A boat’s velocity relative to the water is 5.0 m/s due east. The boat is in a river that flows due north at 3.0 m/s relative to the bank. A passenger throws a ball with a velocity of 8.0 m/s at an angle of 30° north of east, relative to the boat. What is the velocity of the ball as measured by a stationary observer on the bank?
A
10.0 m/s at 36.9° north of east
B
13.5 m/s at 30.4° north of east
C
16.0 m/s at 30° north of east
D
9.3 m/s at 45.6° north of east
