Item 5 (Figure 1) 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 = kmr², where m is its mass, r is its radius, and k is a dimensionless constant between zero and one. The wheel is rotating counterclockwise with angular speed 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. Figure F < 1 of 1 Part A Suppose that after a certain time t, the string has been pulled through a distance L. What is the final rotational speed Wfinal of the wheel? Express your answer in terms of L, F, I, and wo. ► View Available Hint(s) IV-| ΑΣΦ ? Wfinal = Submit Part B What is the instantaneous power P delivered to the wheel via the force at time t = 0? Express the power in terms of some or all of the variables given in the problem introduction. ► View Available Hint(s) VE ΑΣΦ ? P = Submit Provide Feedback
