In the first second of its flight a rocket ejects `(1)/(60)` of its mass with a reative velocity `2073ms^(-1)` What is the initial acceleration of the rocket ? .

A rocket fired from the earth's surface ejects 1% of its mass at a speed of 2000 ms^(-1) in the first second. Find the average acceleration of the rocket in the first second.

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 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 of mass 120kg. Is fired in the gravity free space is ejected gases with velocity 600 m/s at the rate of 1kg/s. what will be the initial accleration of the rocket:-

A rocket of initial mass 6000kg ejects mass at a constant rate of 16kg//s with constant relative speed of 11m//s What is the acceleration of the rocket one mnute after blast ?

A rocket of total mass 1000kg initially is launched from ground. The gases are ejected at the rate 20kg/s with velocity 1000 m/s relative to rocket vertically downwards. The initial acceleration of the rocket is a (in m//s^(2) ). Find a/g . (Take g=10 m//s^(2) )

A rocket of initial mass 6000 kg ejects gases at constant rate of 20 kg//s with constant relative speed of 8 km//s . What is the acceleration of the rocket after 100 s . (a) Neglect gravity , (b) include gravity and (c ) upward thrust.

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

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
