hey i was wondering if i could get a little help with rotation problems... with the angular velocity and all. so far i know Θ=s/r and V=wr
i need help with converting rpm to mph and vice versa.
one problem from a test: A bicycle with 27 in. diameter wheels is going 23 mph. At what rate are the wheels rotating? (how would i solve this problem) also they want the answer in RPM.
thanks for any help,
