Compute all parts of given question:

Question: Modern wind turbines are larger than they appear, and despite their apparently lazy motion, the speed of the blades tips can be quite high-many times higher than the wind speed. A turbine has blades 58m long that spin at 13rpm.

Part A: At the tip of a blade, what is the speed?

Part B: At the tip of a blade, what is the centripetal acceleration?

I need expert help to solve the above question.
