Centripetal force is just mass times centripetal acceleration (F=ma). You know the mass, so how do you calculate centripetal acceleration?

anonymous · Answer

Remember, centripetal force is here a result of the friction between road and bicycle wheels. mv^2/r is the formula, plug and chug to get c.
