The kinetic energy of the body is least in one of the following phases of the walking cycle: (A) Heel strike, (B) Mid-stance, (C) Double suppo, (D) Toe-off
Answer is B. 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).
