Answer:

Option B is the correct answer.

Step-by-step explanation:

Angular velocity of the driver = 20 rad/s

The axis of rotation is 2.0 m.

Radius of rotation = 2 m

Linear velocity of the club head = Angular velocity of the driver x Radius of rotation

Linear velocity of the club head = 20 x 2 = 40 m/s

Option B is the correct answer.
