A small piece of cork in a ripple tank oscillates up and down as ripples pass it. If the ripples travel at 0.20m/s, have a wavelength of 15mm and an amplitude of 5.0mm, what is the maximum velocity of the cork?

Answer 1

The answer is 0.419m/s

Answer 2

.5m

Answer 3

Wavelength of ripples

Answer 4

.44 m/s

Answer 5

y means lambda

v= fy
y- 15mm= 0.015m
A- 5mm= 0.005m

0.2= f*0.015
f= 0.2/0.015= 40/3 Hz

w=2πf
w= 2*22/7*40/3= 83.81

V(max)= wA
= 83.81*0.005= 0.42m/s
