Answer 1

Answer #1

Kindly go through the solution provided below.

Work done on the system is negative. Therefore, we are getting a negative value for the work done.

The the system is the weight of 500 kg and the cable.

cable by = so 200 500kg work done to pull the an anourt dy dw= f(y).dy I Net force acting p=2kg/m downward due to the weight

Brad tries out a weight-loss plan that involves repeatedly lifting a 42.9-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 37.1 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...
