In moving traffic you see the car you are tailgating kinda bumping up and down, due to a big clump of snow stuck on one side of a rear tire. The radius of the tire is approximately 26.4cm. Traffic is moving at 5.95m/s. (a) What is the period of the car's motion up and down? (b) The snow clump is located at a distance of 19.9cm from the axis of rotation of the wheel. Determine the tangential velocity of the bump.
