A diwali rocket is ejecting `0.05kg` of gases per second at a velocity of `400m//sec`. The accelerating force on the rocket is

A Diwali rocket is ejecting 5 gram of gases/second at a velocity of 4m/s. What is the accelerating force acting on the rocket?

A rocket is ejecting g 50 of gases per sec at a speed of 500m//s . The accelerating force on the rocket will be

At a certant of time the mass of a roket going up vertically is 100kg. If it is ejecting 5kg of gas per second at a speed of 400m//s , the acceleration of the rocket would be ("talking" g=10m//s^(2))

A 2000 kg rocket in free space expels 0.5 kg of gas per second at exhaust velocity "400 m s"^(-1) for 5 s. The increase in the speed of the rocket in this time is

A rocket burns 0.5 kg of fuel per second ejecting it as gases with a velocity of 1600 m//s relative to the rocket . How much force is exerted on the rocket ? Also , calculate the velocity attainted by the rocket , when its mass reduces to (1)/(200) th of its initial mass .

If M is mass of rocket, r is rate of ejection of gases and u is velocity of gases with respect to rocket then acceleration of the rocket dv/dt is equal to

A rocket of mass 1000 kg exhausts gases at a rate of 4 kg /sec with a velocity 3000 m//s . The thrust developed on the rocket is

In a rocket, fuel bums at the rate of 1 kg/s. This fuel is ejected from the rocket with a velocity of 60 km/s. This exerts a force on the rocket equal to
