Question

The world’s largest wind turbine has blades that are 80 m long and makes 1 revolution every 5.7 seconds. What is the velocity for one of the blades? (THIS IS physics, CIRCULAR MOTION)?

Answer 1

Answer:

The free end of the blade has a tangential velocity of about 88.19 m/s

Explanation:

The angular velocity of the blades is  $2 \pi /5.7\,\,rad/sec$

since the blades are 80 m long, then the tangential velocity of the free end of the blade is:

$v_{tan} \approx 88.19\,\,m/s$
