A place of cork is floating on water in a small tank. The cork oscillates up and down vertically when small ripples pass over the surface of water. The velocity of the ripples being `0.21 ms^(-1)`, wave length `15 mm`, and amplitude `5 mm`, the maximum velocity of the piece of cork is `(pi = (22)/(7))`
A. `0.44 ms^(-1)`
B. `0.24 ms^(-1)`
C. `2.4 ms^(-1)`
D. `4.4 ms^(-1)`
