Self-oscillation period

The water in the vessel carried by the boy has a self-oscillation period of 0.8 s. What is the size of the boy's movement speed when the length of the boy's step is 60 cm? Give the result in m/s.

Correct result:

v =  0.75 m/s

Solution:

T=0.8 s s=60 cm m=60/100  m=0.6 m  λ=vT s=v T  v=s/T=0.6/0.8=34=34 m/s=0.75 m/s



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
