A car with a total mass of 1.65*103 kg has wheels ofradius 35.0 cm and moment ofinertia 0.760 kg ·m2. Suppose that the wheels were then replaced by oversized wheels of the same shape and made of the same materials,but 49% wider and with a 49% larger radius. By what factor would the rotational energy increase?
