Aswimming duck paddles the water with its feet once every 1.6 s, producing surface waves with this period. the duck is moving at constant speed in a pond where the speed of surface waves is 0.32 m/s, and the crests of the waves ahead of the duck are spaced 0.12 m apart. (a) what is the duck's speed? (b) how far apart are the crests behind the duck?
Answers: 3
= speed of duck ahead of wave 
= speed of surface wave = 0.32 m/s
= speed of wave behind the duck
