Wheels rotational inertia-engineer is to achieve their goal

Reference no: EM13649039

Engineers redesign a car's wheels with the goal of decreasing eachwheel's angular momentum by 30% for a given linear speed for the car. Other design considerations require that the wheel diameter gofrom 38 {\rm cm} to 36 cm.If the old wheel had a rotational inertia of0. 36 kg \cdot m^2, what must be the new wheel's rotational inertia ifthe engineers are to achieve their goal?
