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.
