# Tire Rotations and Frequency

This content was STOLEN from BrainMass.com - View the original, and get the already-completed solution here!

If a bicycle tire is 66 cm in diameter. (a) At what frequency does the tire rotate when the bicycle is traveling at a speed of 30 km/h? (b) What is the angular frequency? Please show all work and formulas and the final answer. The final answer should be (a) 4.0Hz and (b) 25 rad/sec. I need to know exactly how to get those answers.
