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 Diwali rocket is ejecting 0.05 kg of gases per second at a velocity of 200 m//s. The accelerating force on the rocket is :

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

A rocket is ejecting 1 kg of gases per sec at a velocity of 60 km/s. The accelerating force on the rocket is

A rocket burns 50g of fuel per second ejecting it as a gas with a velocity of 5 xx 10 cm s^(-1) . What force is exerted by the gas on the rocket?

A rocket motor consumes 100 kg of fuel per second exhausting it with a speed of 5 km/s. The speed of the rocket when its mass is reduced to (1^(th))/(20) of its initial mass, is ( Assume initial speed to be zero and ignored gravitational and viscous forces. )
