A tractor pulls forward a moving plow with a force of 2.5*10^4N, which is just large enough to overcome friction.

A) what are the action, reaction forces between the tractor and the plow

B) Are these reaction, action forces equal in magnitude and opposite in direction? Will there be any acceleration? Explain.

My ans:

Action/Reaction forces are: Tractor pulling forward on plow and plow pulling backward on tractor..

Yes these forces are equal in size and opposite in direction.

However, I do not understand whether there will be acceleration or not. Does the question mean that there is no friction force now?

I agree with your answers.

Fn = Fap - Ff = ma = 0. a = 0.
Since there is no change in velocity or
speed, there is no acceleration(a=0).
Fn = 25,000 - Ff = 0,
Ff = 25,000N.

Fn = Net force.
Fap = Force applied by tractor.
Ff = Force of friction.

Remember the force of the tractor just
barely overcomes the force of friction.

In order to determine whether there will be acceleration or not, we need to consider the forces acting on the tractor and the plow.

Since the tractor is pulling the plow forward with a force of 2.5*10^4N, we can assume that there is no friction force opposing the motion. This means that the only force acting on the plow is the forward force applied by the tractor. Similarly, the only force acting on the tractor is the backward force exerted by the plow.

According to Newton's third law of motion, the action and reaction forces are equal in magnitude and opposite in direction. Thus, the magnitude of the force applied by the plow on the tractor is also 2.5*10^4N but in the opposite direction.

Now, if there are no other external forces acting on the system of the tractor and the plow, then we can determine the acceleration using Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration.

Let's assume that the combined mass of the tractor and the plow is 'm'. The net force acting on this system is the difference between the forward force applied by the tractor and the backward force exerted by the plow:

Net force = 2.5*10^4N - 2.5*10^4N = 0N

Since the net force is zero, the acceleration of the system is also zero according to Newton's second law. This means that the tractor and the plow will not accelerate and will continue to move at a constant velocity.

Therefore, the answer to the question is that there will be no acceleration in this scenario, assuming that there are no other external forces acting on the system.
