AI Thread Summary
During re-entry, the space shuttle's speed decreases from approximately 8000 m/s to 100 m/s due to the conversion of kinetic energy into thermal energy through friction with atmospheric molecules. This process involves the surface molecules acting like springs, which dissipate energy and contribute to the loss of momentum. The thermal energy generated heats surrounding air molecules, causing them to move faster, thereby conserving momentum in the system. The discussion highlights the importance of understanding energy conversion and momentum conservation during the shuttle's descent. Overall, the explanation reflects a grasp of the underlying physics concepts, though further clarification may be needed.

Homework Statement



As its coming back to Earth from orbit, the space shuttle enters the atmosphere traveling at a speed of roughly 8000 m/s. Just before it lands, its speed has already decreased to about 100 m/s. The gravitational potential energy of the earth-shuttle system has also decreased. Where does all of the shuttle's momentum go?

Homework Equations



There is no equations but knowledge of the spring theory

The Attempt at a Solution



The spring theory is responsible for the loss of momentum. The surface molecules act like spring and turn the kinetic energy into thermal energy through friction causing the shuttle to slow down.

I would like to know if I am going in the correct direction with this or not. . .I don't understand why other questions posted after mine are already answered but my question isn't . . . . what more must I do?
 
Well it would seem that you have grasped the concept of kinetic energy being converted into other forms.
As for the momentum, I would say that the thermal energy heats up the surrounding molecules so they begin to move faster too (conservation of momentum must be conserved), and through friction, the opposing air molecules are being forced downwards.

This is all I can think of for the momentum of the space shuttle, there could be more and my answer might not be completely correct, so please don't accept it as fact.
 
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
