Find rocket thrust, inteval between ignition and lift-off
Mass of the rocket for its weight to become equal to the thrust = 1.85x103 kg
Reduction in mass for the rocket to lift off = 1.9x103 - 1.85x103 = 0.05x103 kg or 50 kg
Rate at which the fuel is consumed = 7.4 kg/s
Time taken to take off = 50/
