How can you create enough thrust to exceed the weight of the rocket?

Answer:

Re-action of the working fluid may exceed the thrust force of the rocket.

Explanation:

A force that moves the rocket through the air present and then through space is known as thrust. This being generated by the 'propulsion system' of the rocket with newton’s third law of motion.  

In the propulsion system, the engine works on the gas or liquid and that is further accelerated for working of the engine. This working fluid expelled in one direction whereas, the thrust force is applied in another direction may help in exceeding the weight of the rocket.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
