A person trying to lose weight lifts a 10 kg mass, one thousand times, to a height of 0.5m each time. Assume that the P.E. lost each time the person lowers the mass is dissipated. Fat supplies 3.8xx10^(7) J of energy per kg which is converted to mechanical energy with a 20% efficiency rate. How much fat will the dieter use up?

A person trying to lose weight (dieter) lifts a 10 kg mass, one thousand times, to a height of 0.5 m each time. Assume that the potential energy lost each time she lowers the massis dissipated:- Fat supplies 3.8 xx 10^7J of energy per kilogram which is converted to mechanical energy with a 20% efficiency rate. How much fat will the dieter use up?

A person trying to lose weight by burning fat lifts a mass of 10 kg upto a height of 1 m 1000 times. Assume that the potential energy lost each time he lowers the mass is dissipated. How much fat will he use up considering the work done only when the weight is lifted up? Fat supplies 3.8 x 10^(7) J of energy per kg which is converted to mechanical energy with a 20% efficiency rate. Take g=9.8 ms^(–2) :

A person trying to lose weight by burning fat lifts a mass of 10 kg upto a height of 1m is 1000 time . Assume that the potential energy lost each time be lower the mass is dissipated . How much far will be use up considering the work done only when the weight is lifted up ? Far supplies 3.8 xx 10^(7) J of energy per kg wich is canverted to mechanical energy with x 20 % efficiency rate Take = 9.8 ms^(-2)
