A jogger with mass m = 55 kg uses energy at a rate of P = 802 W when she jogs on horizontal ground at a constant speed of s = 3.5 m/s. The efficiency of her “human engine” however, is e = 0.27. (In other words, the power used for locomotion is e = 0.27 times the total power.) Q) Write an expression for the rate of energy expenditure whenshe jogs at the same constant speed up a slope of 4.99 degrees. 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(9.80 m/s^2)

Matching heights A stone is thrown with an initial velocity of32 ft/s from the edge of a bridge that is 48 ft above the ground.The height of this stone above the ground t seconds after it isthrown is ƒ(t) = -16t2 + 32t + 48. If a second stone is thrownfrom the ground, then its height above the ground after t secondsis given by g(t) = -16t2 + v0t, where v0 is the initial velocity ofthe second stone. Determine the value of v0 such that both stonesreach the same high point.
