Question

plz help

two rocket ships are out in space. The 1st ship has its engines on, constantly firing. The 2nd ship has its engines on then turns its engines off. Explain what will happen to each rocket ship.

Answer 1

To figure out how to get from Earth to another planet, and to figure out how much fuel will be needed in various cases, we need to start with Newton's laws of motion, again

Answer 2

Newton's First Law: A body will remain at rest or in motion in a straight line unless acted upon by a force.

Newton's Second Law: Change in motion is proportional to the applied force and parallel to it.

Newton's Third Law: To every action there is an equal and opposite reaction.

Answer 3

so all three is working in this

Answer 4

yay

Answer 5

so the first rocket is newtons 1 lae anf the 2 rocket is newtons 2 and 3 law

Answer 6

By Newton's first law, two things are really cheap: Coasting and sitting still. Out in space, sitting still is a little hard to define - do I mean compared with the Sun, or Mars? Also, most of the time we are in an orbit of some sort, so sitting still doesn't really make sense. What we need to think about is how to change from one kind of orbit to another kind of orbit.

Newton's Third Law contains the "secret" of rocket propulsion for space travel. See the figure below. If A exerts a force on B, then B exerts an equal and opposite force on A. Or, in the case of space travel, if a mass (m) of fuel is pushed out the exhaust of a rocket, then the rocket will accelerate in the opposite direction the direction the exhaust fuel went.

Answer 7

awnser is Once a spacecraft has fired its engines for some amount of time, the ship accelerates from rest and reaches some planned speed. When the engines cut off, there is a total lack of any force acting on the spacecraft (this is, again, assuming that the spacecraft is in deep space and not near any planets).

Answer 8

ok i am still a little confused but i try to get it

thanks
