• A jogger with mass m=85kg uses energy at a rate of P=744W when she jogs on horizontal ground at a constant speed of s=3.9m/s.The efficiency of her"human engine"however, is e=0.36.(In other words, the power used for locomotion is e=0.36times the total power.)

• A. write expression for the rate of energy expenditure when she jogs at the same constant speed up a slope of\phi=4.26degrees. Assume whatever frictional or drag forces are the same in each case. Your answer should be in terms of the symbols given in the problem statement and g(9.80m/s2). Answer= P+mgs(sinO)/e

B. What is the rate of energy expenditure when she jogs up the slope, in watts?

P=
