Example: A small rocket with an initial mass of 400 kg, is to be launched vertically. Upon ignition the rocket consumes fuel at a rate of 5 kg/s and ejects gas at atmospheric pressure with a speed of 3500 m/s relative to the rocket. Determine the initial acceleration of the CV rocket and the rocket speed after 10 seconds, if the air resistance is neglected.

Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.
