Module 6 Quiz Begin Date: 9/ (5%) Problem 11: A jogger with mass m = 85 kg uses energy at a rate of P = 833 W when she jogs on horizontal ground at a constant speed of s = 2.8 m/s. The efficiency of her "human engine" however, is e = 0.31. (In other words, the power used for locomotion is e = 0.31 times the total power.)
