The centripetal acceleration of the bicycle ha, A bicycle chain is wrapped around a rear sprocket ( r = .039,m ) and a front sprocket ( r = 0.10,m ) the chain moves with a speed of 1.4, m/s around the sprockets while the bike moves at a constant velocity. Then, the brakes are applied, and the bike is brought to a uniform stop. The driver steps on the accelerator and in a time of 12.0 s the angular velocity increases to +30, A cyclist starts from rest and pedals such that the wheels of his bike have a constant angular acceleration. The radius of each tire is 0.280m. A force of 10 N is applied to an object which accelerates it at 2 m/s2 to the right. Can a car move around a racetrack so that it has tangential acceleration but no centripetal acceleration?
