<prompt> The kinetic energy of the body is least in one of the following phases of the walking cycleHeel strikeMid-stanceDouble suppoToe-off  <response>: B. i.e. Mid stance phaseSpeed so the kinetic energy is maximum in double suppo phase i.e. heel strike, foot flat, toe flat minimum in single suppo phase i.e. midstance, mid swing, heel off.
