Question

During a golf drive, the angular velocity of the driver is 20 rad/s just before impact with the golf ball. If the distance from the club head to the axis of rotation is 2.0 m, what is the linear velocity of the club head? Group of answer choices 10 m/s 40 m/s 20 m/s 40 rev/s 40 rad/s

Answer 1

Answer:

Option B is the correct answer.

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.
