A 2.00 kg ball on a massless string is being spun around in a horizontal circle. The distance from the axis of rotation to the centre of mass of the ball is r = 0.680 m. If the ball has an angular momentum of 3.70 kg . m /s, what is the tangential velocity. of the ball? Enter your answer to two decimal places with units of metres per second, but do not include units in your answer. axis of rotation r ...... . ... . . . ............ Your Answer: Your
