A transverse water wave is moving along the surface of some water. This causes a ball to move vertically without moving horizontally as it floats upon the surface. At one instant, the ball is at the position shown. [Figure 22.1] The wave has a frequency of 0.20 Hz and an amplitude of 0.70 m. The distance between a trough and an adjacent peak is 2.4 m. What is the distance travelled by the ball in a time of 20 s?
A5.6 m
B9.6 m
C11.2 m
D19.2 m
