A student decides to give his bicycle a tune up. He flips it upside down (so there’s no friction with the ground) and applies a force of 20 N over 1.2 seconds to the pedal, which has a length of 16.5 cm. If the back wheel has a radius of 33.0 cm and moment of inertia of 1200 kg·cm^2, what is the tangential velocity of the rim of the back wheel in m/s? Assume he rides a fixed gear bicycle so that one revolution of the pedal is equal to one revolution of the tire. Round your answer to 1 decimal place for entry into eCampus. Do not enter units. Example: 12.3
