Question

When kicking a football, the kicker rotates his leg about the hip joint. If the velocity of the tip of the kicker’s shoe is 35.0 m/s and the hip joint is 1.05 m from the tip of the shoe, what is the shoe tip’s angular velocity?

Answer 1

33.33 rad / s

Step-by-step explanation:

Linear velocity = 35 m/s

Radius = 1.05 m

The relation between the linear velocity and the angular velocity is given by

Linear velocity = radius × angular velocity

Angular velocity = linear velocity / radius

Angular velocity = 35 / 1.05

= 33.33 rad/ s
