ok i need help on where to begin this problem because i am lost. any help would be appreciated thank you

A windmil has 8 blades and rotates at an angular speed of 1.25 radians/second. the opening between succesive blades is equal to the width of of a blade. a golf ball of diameter 4.50*10 -2m is just passing by one of the rotating blades. what is the minimum speed of the ball so that it will not be hit by the next blade?

thnk you for your time
