A bicycle wheel is mounted on a fixed, frictionless axle, with a light string wound around its rim. The wheel has moment of inertia I=kmr[squared], where m is its mass, r is its radius, and k is a dimensionless number between zero and one. The wheel is rotating counterclockwise with angular velocity Wo, when at time t=0 someone starts pulling the string with a force of magnitude F.Assume that the string does not slip on the wheel.A. Suppose that after a certain time tL, the string has been pulled through a distance L. What is the final rotational speed of the wheel? B.What is the instantaneous power delivered to the wheel via the force F at time T=0? *Please see attachment for proper citation of symbols as well as diagramPulling a String Adds Energy to a Wheel .Assume that the string does not slip on the wheel. . What is the final rotational speed of the wheel? . ?Express the power in terms of the variables given in the problemintroduction. [  HYPERLINK "javascript:window.print();" Print  ]
