How much energy was absorbed by the person's body? Express your answer using two significant figures. Submit My Answers Give U Part B Compare this energy to the amount of energy absorbed by a person's body if they jumped from a chair to the floor assume that all of the energy from the fall is absorbed by the person and h 3 0.5m). Express your answer using two significant figures. Subm My Answers Give U Continue Provide FeedbackExplanation / Answer
1rad= 0.01J/Kg. 32.8 Rad correspond to 32.8*0.01 j/kg =0.328 J/kg
mass of the body= 80 kg
so energy absorbed= 80*0.328 joules=26.24 joules
b) Potential energy= mgh, where m= 80 kg, g= 9.8 m/sec2 and h=0.5m
potential energy= 80*9.8*0.5=392 joules
