    please I need help on rotational velocity problem for tomorow dec 7

    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?
