+ FIGURE 1: Wind tunnel experiment to measure how the force of air resistance depends on velocity. A free-falling object such as a bungee jumper is subject to the upward force of air resistance. We assumed that this force was proportional to some power b of velocity as in Fu=CVb where Fu = the upward force of air resistance [N = kg m/s²], C = drag coefficient (kg/m), and V = velocity [m/s]. An individual is suspended in a wind tunnel and the force measured for various levels of wind velocity. The result might be as listed in Table 1 V (m/s) Fu (N) 15 65.5 30 227.9 45 60 472.9 793.7 75 1186 90 1646.7 Table 1: Experimental data for force (N) and velocity (m/s) from a wind tunnel experiment. Find least sqaures approximation Fu=CVb to the data given in Table 1.
