Unformatted text preview: v ( t ) = mg c 1 − e − ct m # $ % & ' ( Let us assume we know that the gravitational constant g =9.81 N/kg. In order to estimate the mass m that is falling through the air and the coefficient of viscous friction c , we snap measurements of velocity at time t=5s and t=10s. We obtain that v (5) = 31.1 m/s, and v (10) = 40 m/s. Start with the initial guess of m = 30 kg and c = 0.1 N/(m/s). Perform 5 iterations of the multivariate Newton Raphson method and please show your steps for full credit. Please feel free to use any software and/or programming tool at your disposal (if you do, please enclose the listing of your program). Please enclose your results neatly tabulated so that we can run through your results with ease. Also, please report just 4 decimal digits in your work – thanks!...
