3. The upward velocity of a rocket can be computed by the following formula: mo v = u In- mo - qt 9 where v = upward velocity, u = the velocity at which fuel is expelled relative to the rocket, m, = the initial mass of the rocket at time t = 0,9 = the fuel consumption rate, and g = the downward acceleration of gravity (9.81 m/s2). If u = 1800", mo = 160,000 kg and q = 2600 kg/s, compute the time at which v = 750 m/s. Determine the result so that A
