The blades of a wind turbine are 30 feet long. The propeller rotates at 25 revolutions per minute. a. Find the angular speed of the propeller in radians per minute. b. Find the linear speed of the tips of the blades in miles per hour.
Added by Allison L.
Step 1
The angular speed is the rate at which the propeller rotates. One full revolution is equal to 2π radians. So, if the propeller is making 25 revolutions per minute, the angular speed is 25 * 2π = 50π radians per minute. Show more…
