Unformatted text preview: m falling with initial velocity zero through the air (gaseous fluid) with the coefficient of linear friction c is described as a function of time by the following equation (you will learn this in ME344): 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 of the paraglider m and the coefficient of viscous friction c , we snap measurements of velocity at time t=5s and t=10s. We obtain that v (5) = 29.9 m/s, and v (10) = 40 m/s. Start with the initial guess of m = 70 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 a description how you did it or the listing of your program)....
