2. (8 pts.) The upward velocity of a rocket can be computed by the following formula: mo v = uln mo - qt. - gt where v = upward velocity, u = the velocity at which fuel is expelled relative to the rocket, mo = the initial mass of the rocket at time t = 0, q = the fuel consumption rate, and g = the downward acceleration of gravity (assumed constant = 9.81 m/s2). If u = 2000 m/s, mo = 150,000 kg, and q = 2700 kg/s, compute the time at which v = 750 m/s via a. Graphical method b. Fixed-point iteration method c. Newton-Raphson method d. Secant method Please take Et = 0.1 % for all calculations. For part a you may use a spreadsheet. Please submit a written solution for parts b, c, and d
