Halliday, Resnick & Walker — Temperature, Heat, and the First Law of Thermodynamics: Problem 89

BIO An athlete needs to lose weight and decides to do it by “pumping iron.” (a) How many times must an 80.0 kg weight be lifted a distance of 1.00 m in order to burn off 1.00 lb of fat, assuming that that much fat is equivalent to 3500 Cal? (b) If the weight is lifted once every 2.00 s, how long does the task take?

📝 Solution Approach

Given: 80.0 kg, 1.00 m, 1.00 lb

Find: (a) How many times must an 80; (b) If the weight is lifted once every 2
