A wheel has eight spokes and a radius of 37.5 cm. It is mounted on a fixed axle and is spinning at 3.75 rev/s. You want to shoot a 17.0 cm long arrow through the wheel, parallel to this axle, without hitting any of the spokes. Assume that the arrow and the spokes are very thin and evenly spaced. What minimum speed must the arrow have?
I just riffled off a few random calculations right away:
radian between the spokes = .7853 radians
radial velocity = .033 rad/sec
I'm not sure what to do after that
