Answer:
A
Explanation:
the bill of right was the outlined document.
Answer:
a) 12.56 rad per minute
b)62.8 inches per minute
Explanation:
Given:
- Radius of the blades, R=5 inches
- Frequency of the blades, f=2 revolutions per minute
a)
Let
be the angular velocity of the blade which is given by
![\omega =2\pi f\\\omega=2\times 3.14 \times 2\\\omega=12.56\ \rm rad/min](https://tex.z-dn.net/?f=%5Comega%20%3D2%5Cpi%20f%5C%5C%5Comega%3D2%5Ctimes%203.14%20%5Ctimes%202%5C%5C%5Comega%3D12.56%5C%20%5Crm%20rad%2Fmin)
b)
Let v be the linear speed of the tip of the blade which is given by
![v=\omega \times R\\v=12.56\times 5\\v=62.8\ \rm inches/min](https://tex.z-dn.net/?f=v%3D%5Comega%20%5Ctimes%20R%5C%5Cv%3D12.56%5Ctimes%205%5C%5Cv%3D62.8%5C%20%5Crm%20inches%2Fmin)
Hence we have calculated the angular velocity and linear speed.
Answer:
I think it's Answer A. Because the ball eventually came to a stop, infering that the energy was used up. Hope this helped! :)
