An adult weighing 600 N raises the centre of gravity of his body by 0.25 m while taking each step of 1 m length in jogging. If he jogs for 6 km, calculate the energy utilised by him in jogging assuming that there is no energy loss due to friction of ground and air. Assuming that the body of the adult is capable of converting 10% of energy intake in the form of food, calculate the energy equivalents of food that would be required to compensate energy utillsed for jogging.

Question
An adult weighing 600 N raises the centre of gravity of his body by 0.25 m while taking each step of
1 m length in jogging. If he jogs for 6 km, calculate the energy utilised by hinm in jogging assuming
that there is no energy loss due to friction of ground and air. Assuming that the body of the adult is
capable of converting 10% of energy intake in the form of food, calculate the energy equivalents of
food that would be required to compensate energy utillsed for jogging.
