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.

Result

v =  0.75 m/s

Solution:

T=0.8 s s=60 cm=60/100 m=0.6 m  λ=vT s=v T  v=s/T=0.6/0.8=34=0.75 m/sT=0.8 \ \text{s} \ \\ s=60 \ cm=60 / 100 \ m=0.6 \ m \ \\ \ \\ λ=v T \ \\ s=v \cdot \ T \ \\ \ \\ v=s/T=0.6/0.8=\dfrac{ 3 }{ 4 }=0.75 \ \text{m/s}



Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
