363588 Assertion :
A rocket works on the principle of conservation of linear momentum.
Reason :
Whenever there is a change in momentum of one body, the same change occurs in the momentum of the second body of the same system but in the opposite direction.

363589 If the thrust force on a rocket which is ejecting gases with a relative a velocity of \(300\,m/s\), is \(210\,N\). Then rate of combusting of the fuel will be

363590 An open top railway wagon of mass \(5 \times {10^3}kg\) moves at initial velocity of \(1.2\,m/s\) without friction on railway track. Rain falls vertically downward into the wagon. What change then occured in the kinetic energy of the wagon, when it has collected \({10^3}kg\) of water?

363591 A rocket of mass 1000 \(kg\) is to be projected vertically upwards. The gases are exhausted vertically downwards with velocity \(100\,m{s^{ - 1}}\) with respect to the rocket. What is the minimum rate of burning of fuel, so as to just lift the rocket upwards against the gravitation attraction? (take,\(g = 10\,m{s^{ - 2}}\))

363592 A rocket with a lift-off mass 20000 \(kg\) is blasted upwards with an initial acceleration of \(0.5\,m/{s^2}\). Calculate the initial thrust (force) of the blast.
