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?

Answer 1

Linear velocity of the club head is 40 m/s

Step-by-step explanation:

To calculate the linear velocity of the club head, we just need to multiply the angular velocity of the driver (Av = 20 rad/s) by the distance from the club head to the axis of rotation (d = 2.0 m)

So, the linear velocity of the club head (Lv) is:

Lv = Av * d = 20 * 2 = 40 m/s
