(I'm using negative to indicate the downward direction and x=upward force)
-5782 + x = 5006
x = 10,788 N
Is this the final answer? (and also thank you for taking the time to explain to me what net/thrust/normal force all mean)
The thrust force? But my question is how do i calculate that? I have only learned formulas for frictional, gravitational, and normal force. I don't understand "thrust" force. Can't I just use F=ma? If not, what do I do?
So I drew the FBD of the rocket and I have one arrow going upward for the normal force and one arrow going downward for the gravitational force. I haven't learned any other forces besides frictional force, so I am still not quite understanding exactly what you mean by the rocket motor producing...
