A fully fueled rocket has a mass of 21000 kg, of which 25000 kg is fuel. The burned fuel is exhausted at a rate of 190 kg/s at a speed of 2800 m/s relative to the rocket. If the rocket is fired vertically upward, calculate....

a.) The trust of the rocket

b.) The net force on the rocket at blastoff and just before burnout (when all the fuel has been used up)

c.) The rocket's velocity at burnout

*** Ignore air resistance and assume the acceleration due to gravity is constant at g = 9.8 m.s***

    A 2590-kg test rocket is launched vertically from the launch pad. Its fuel (of negligible mass) provides a thrust force so that its vertical velocity as a function of time is given by v(t)=At+Bt2, where A and B are constants and time is measured from the instant the fuel is ignited. At the instant of ignition, the rocket has an upward acceleration of 2.00 m/s2 and 1.60 s later an upward velocity of 2.46 m/s . At 4.30 s after...

    A rocket accelerates by burning its onboard fuel, so its mass decreases with time. Suppose the initial mass of the rocket at liftoff (including its fuel) is m, the fuel is consumed at rate r, and the exhaust gases are ejected with constant velocity v_e (relative to the rocket). A model for the velocity of the rocket at time t is given by the equation v(t) = -gt - v_e ln m - rt/m where g is the acceleration due...
