A rocket weighs 13,500 kg when fuelled up on the launching pad . It is fired vertically upward . Gases are exhausted at the rate of 145 kg per second with velocity 1500 `ms^(-1)` relative to the rocket . What is the thrust on the rocket ?

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 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

A rocket of mass 5000 kg is to be projected vertically upward. The gases are exhausted vertically downwards with velocity 1000ms^(-1) with respect to the rocket. What is the minimum rate of burning the fuel so as to just lift the rocket upwards against gravitational attraction ?

A rocket of mass 1000 kg is to be projected vertically upwards. The gases are exhausted vertically downwards with velocity 100m//s with respect to the rocket. (What is the minimum rate of burning fuel, so as to just lift the rocket upwards against the gravitational attraction?) (Take g=10m//s^(2) )
