A typical candy bar weighs about 2 oz (1.00 oz= 28.4 g).(a) Assuming that a candy bar is 100% sugar and that 1.0 g of sugar is equivalent to about 4.0 Calories of energy, calculate the energy (in kJ) contained in a typical candy bar.(b) Assuming that your mass is 58 kg and you convert chemicalpotential energy to work with 100% efficiency, how high wouldyou have to climb to work off the energy in a candy bar? (Poten-tial energy =mass XgXheight, where g=9.8 m/s².)(c) Why is your actual conversion of potential energy to workless than 100% efficient?
