Here are my rocket's pictures:

Do you know how to stabilize my rocket?
I did a bottle rocket yesterday (2 liter bottle). I made 4 fins and the end of the fins touch the ground instead of the bottle's opening. I also equip my rocket with a parachute (hide under the nose cone). In addition, I added a modeling clay to my nosecone too! When I tested it, my teacher said...
But if the astronaut is floating in the space, do you know what forces can exert on him and the other opposite force (reaction) (it's not gravity right?)
So, back to your example, if there is a man is standing on a table, he exerts a force on a table and a table also exerts an opposite equal...
As I learn about Newton's Third Law:For every force applied to object A by another object B, there is an equal and opposite force(reaction) applied to object B by object A.
I think if we had two equal and opposite forces exerts on a thing so it will not move!
Also, if there is an astronaut...
It's very helfull but I want to ask you that are there some factors that affect the stopping distance? like, time, speed.. or something like that?
Is there a formula to calculate the stopping distance in my example above?
I don't understand these words: stopping distance and reaction time! Can anyone show me how to solve or the formula of stopping distance and reaction time!
What are the factors affect the stopping distance?
Like, there is a car is traveling at 70 m/hr, and its reaction time is 2 seconds...
Typically, I've just gone to a new school this semester and the teacher gave me these questions, I knew how to solve velocity, time, distance but the word "reaction time" seems new to me, so that I don't know how to do do these problems
1. An automobile is traveling at 60 feet/sec (40mph).
a) If the reaction is 0.5 seconds, how far does the automobile travel in this time?
b) How much farther will the automobile travel if the driver is distracted by talking on a cellphone, so that the reaction time increases to 1.5 seconds...
