Question

The cork in Question 1 travels I foot in moving from its lowest position to its highest position. What is the average velocity of the cork during this motion?

Answer 1

Answer:

8ft/s

Explanation:

For computing the average velocity of the cork first we have to determine the frequency which is shown below:

$Frequency = \frac{Time\ taken }{one\ minute}$

$= \frac{240}{60\ seconds}$

= 4 Hz

Now the average velocity of the cork is

$\frac{\lambda}{2} = 1 ft\\\\ \lambda = 2ft\\\\ velocity = f\times \lambda$

= 8ft/s

We simply applied the above formulas to determine the frequency and the velocity of the cork during this motion and the same is to be considered
