The mass of the gas emitted from the rear of a toy rocket is initially 0.1kg / s. If the speed of the gas relative to the rocket is 500 m/s and mass of rocket is 2kg .what is the initial acceletion of the rocket `(g=10m/s^2)`

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 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) )

The force on a rocket moving with a veloctiy 300 m/s is 210N. The rate of consumption of fuel of rocket is

A rocket of mass 20000 kg is ejecting the gases at the rate of 50 kg/sec with speed of 20 m/sec in gravity free space. Find the acceleration of rocket at 2 sec.

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 mass 40kg has 160kg fuel. The exhaust velocity of the fuel is 2.0km//s . The rate of consumption of fuel is 4kg//s . Calculate the ultimate vertical speed gained by the rocket. (g=10m//s^2)

A rocket, with an initial mass of 1000kg , is launched vertically upwards from rest under gravity. The rocket burns fuel at the rate of 10kg per second. The burnt matter is ejected vertically downwards with a speed of 2000ms^-1 relative to the rocket. If burning ceases after one minute, find the maximum velocity of the rocket. (Take g as constant at 10ms^-2 )

A rocket of mass 5700 kg ejects mass at a constant rate of 15 kg/s withe constant speed of 12 km/s. The acceleration of the rocket 1 minute after the blast is (g=10m//s^(2))

A rocket is moving in a gravity free space with a constant acceleration of 2 m//s^(2) along + x direction (see figure). The length of a chamber inside the rocket is 4 m . A ball is thrown from the left end of the chamber in + x direction with a speed of 0.3 m//s relative to the rocket . At the same time , another ball is thrown in + x direction with a speed of 0.2 m//s drom its right end relative to the rocket . The time in seconds when the two balls hit each other is

A 800 kg rocket is fired from earth so that exhaust speed is 1200 m/s. Then calculate mass of fuel burning per second, to provide initial thurst to overcome its weight. (g=10m//s^(2)) .
