The use of a wind-powered energy is becoming more and more prevalent around the world to produce clean energy. A windmill with a blade 60 feet long rotates at a rate of 50 revolutions per minute. What is the linear velocity of the tip of the windmill blade? The linear velocity of the tip of the windmill blade is ft/min (Type an integer or decimal rounded to the nearest tenth as needed.)

Solution

V is the linear velocity
V=r*w
w is omega, w=2*pi*50=314.2857
r is the radius of blade=60
V=60*314.2857
V=18857.1 ft/m
