Problem 68

By measuring oxygen uptake, sports physiologists have found that long-distance runners power output is given approximately by P = m1bv - c2, where m and v are the runners mass and speed, and b and c are constants given by b = 4.27 J/kg # m and c = 1.83 W/kg. Determine the work done by a 54-kg runner who runs a 10-km race at 5.2 m/s.

Step 1 of 3

Dudaie 1 Physics II Chapter 20­ Electric Potential and Electric Potential Energy 1. Electric Potential Energy and the Electric Potential a. Electrical and gravitational forces have many similarities (both conservative forces) i. As a result there is an electric potential energy (U), similar to the gravitational potential energy; since U is equivalent to ­W done. 1. Associated with electrical force a. ΔU = ­W = qEd ii. As far as electrical potential (V) is the electrical potential energy per charge 1. Δ
