Suppose a rocket with an intial mass `M_(0)` eject a mass `Deltam` in the form of gases in time `Deltat`, then the mass of the rocket after time t is :-

A rocket is ejecting a mass m of gases per unit time with velocity V relative to the rocket, the thrust on the rocket is:

A rocket of initial mass m ( including fuel) ejects mass at a constant rate of 25 kg/s with a speed 60 m/s relative to the rocket. If the acceleration of the rocket 3.5 minutes after the firing is 2m//s^(2) . What is the initial mass of the rocket ? [Neglect gravity] Express your answer in unit of 10^(3) kg

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 initial mass 6000kg ejects mass at constant rate of 200 kg/sec. with constant relative speed of 800 m/sec. The acceleration of the rocket after 5 sec is (neglect gravity)

A rocket of initial mass 6000kg ejects mass at constant rate of 200 kg/sec. with constant relative speed of 800 m/sec. The acceleration of the rocket after 5 sec is (neglect gravity)
