Okay, so that means T1 is the same as T2.

Oh, right. So NetF is 0. Which means that on each side it is pulling the exact same? Does that have to do with Newton's third law?

The tension of a rope is the always the same on any side of a rope, right? Why is that?

probably not? i guess just the mass of the car as a whole?

freebody diagram, kinda. is it where you draw a cartesian plane then draw arrows in different directions? so what you mean is that i could solve this as one, or split it into two?

Could anyone help with the second question?

So if a is 0 then F=0, cause if you multiply something by 0 then it will be 0. So in that case the plane is in dynamic equilibrium, so the thrust has to be 1800N? So the net force is 0?

Net force is the sum of all the forces acting on an object. The equation for net force is mass times acceleration. I guess the grav. force and the lift balance the plane vertically, and we are given that there is 1800N drag.

So the net force is 1800N East?

If the object is moving forward at 1800N and it is in constant velocity, that means that it should be in equilibrium, so that means there would be a 1800N thrust? I am so confused. If the plane is moving forward and isn't going anywhere, how is it moving? Or am I doing something wrong...

The acceleration would be zero.

Well... I am stuck on them. I will try my best I guess. 1. So for the first one I know that Net force is equal to all the forces acting on it. So Drag would be in the left direction if the plane was going right. Since it's a constant velocity, that means they balance out (I think!). So is it...

Hello, I am taking physics (freshman, high school) and I am very confused on the current topic. We are learning about Newton's first, second and third laws. Our teacher speaks very fast and I cannot seem to understand many topics that he talks about. Questions I am confused on: 1. A plane is...
