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

88.14 m/s

Step-by-step explanation:

From the question given above, the following data were obtained:

Radius (r) = length of blade = 80 m

Revolution (rev) = 1

Time (t) = 5.7 s

Velocity (v) =?

The velocity of the blade can be obtained by using the following formula:

v = (rev × 2πr) / t

NOTE: Pi (π) = 3.14

v = (1 × 2 × 3.14 × 80) / 5.7

v = 502.4 / 5.7

v = 88.14 m/s

Therefore, the velocity of the blade is 88.14 m/s
