For a Rocket propulsion velocity of exhaust gases relative to rocket is 2km/s. If mass of rocket system is 1000 kg, then the rate of fuel consumption for a rockt to rise up with acceleration `4.9 m//s^(2)` will be:-

The exhaust velocity of gases with respect to a small rocket of mass 25 kg. is 28xx10^(2)m//s . At what rate the fuel must burn so that it may rise up with an acceleration of 9.8 m//s^(2) ?

The exhaust velocity of gases with respect to a small rocket of mass 25 kg. is 28xx10^(2)m//s . At what rate the fuel must burn so that it may rise up with an acceleration of 9.8 m//s^(2) ?

The exhaust velocity of gases with respect to a small rocket of mass 25 kg. is 28xx10^(2)m//s . At what rate the fuel must burn so that it may rise up with an acceleration of 9.8 m//s^(2) ?

The rate of mass of the gas emitted from the rear of a rocket is initially 0.1 kg//s . If the speed of the gas relative to the rocket is 50 m//s and the mass of the rocket is 2 kg , then the acceleration of the rocket in m//s^(2) is

The mass of a rocket is 500 kg and the relative velocity of the gases ejecting from it is 250 m/s with respect to the rocket. The rate of burning of the fuel in order to give the rocket an initial acceleration 20 m//s^(2) in the vertically upward direction g = 10 m/s^(2) , will be -

A rocket is set for a vertical firing . If the exhaust speed is 2000 m//s , find the rate of fuel consumption initial vertical upward acceleration of 30 m//s^(2) . Take mass of rocket = 6000 kg .
