At the instant shown, the rocket is traveling straight up at 100 m/s. Its mass is 90.000 kg and the thrust of its engine is 2400 kN Aerodynamic drag exerts a resisting force (in newtons) of magnitude 0.8v2, where v is the magnitude of the velocity. How long does it take for the rocket’s velocity to increase to 200 m/s?
