A student is conducting an experiment to measure the rotational inertia of a bicycle wheel. The student measures the mass M And radius Of the wheel. The student wraps string around the wheel several times and then the free end of the string to the ceiling. The student releases the wheel from rest so that the wheel falls and rolls from the string. For each of the following parts, a full-credit response would state additional equipment the student would need, how the equipment would be used, what measurements are to be made, and what equations would be used and how they would be used. (a) Explain how the student can determine the linear acceleration of the center of the wheel as it falls toward the floor. (b) Explain how the student can determine the angular acceleration of the wheel. (c) Explain how the student can determine the tension in the string.
