Can a Rocket Surpass the Speed of Its Exhaust Gases?

AI Thread Summary
A rocket can theoretically achieve a speed greater than the velocity of its exhaust gases when considering its momentum and impulse. The relationship between the rocket's velocity and the exhaust gases depends on the reference frame, particularly whether it is measured relative to the gas or the ground. Analyzing the rocket's motion requires deriving an expression for its velocity as a function of time, which incorporates the mass flow rate of the exhaust and the initial mass of the rocket. This analysis reveals that as the rocket expels gas, it can accelerate beyond the speed of the exhaust relative to the ground under certain conditions. Understanding these dynamics is crucial in rocket propulsion and performance analysis.

is it possible for a rocket to attain a speed greater than the velocity with which exhuast gases leave it? explain.

I am not sure about this, because relative to the gas, I think yes, but I am not sure if it is also greater relative to the ground. This question is from momentum/impulse unit, so can you explain this concept in those terms?

Derive an expression for the velocity of the rocket as a function of time. See what you can deduce from it.
 
Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
