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
b)
Let v be the linear speed of the tip of the blade which is given by
Hence we have calculated the angular velocity and linear speed.
