Brad tries out a weight-loss plan that involves repeatedly lifting a 41.4-kg barbell from the floor over his head to a height of 2.00 m. If he is able to complete three such lifts per minute, how long will it take for him to lose 0.50 kg of fat? “Burning” 1 g of fat supplies 38.6 kJ to the body; of this, 10.0% can be used by the muscles to lift the barbell. (Ignore the fat “burned” while he lowers the barbell to the floor.)
