Test Academy | An unloaded bus and a loaded bus are both moving with the same kinetic energy. The mass of the latter is twice that of the former. Brakes are applied to both, so as to exert equal retarding force. If x1 and x2 be the distance covered by the two buses respectively before coming to a stop, then x1=x2, 2x1=x2, 4x1=x2, 8x1=x2
