Two people are pushing a couch from opposite sides. One person is pushing to the right with a force of 3 N. The other person is pushing to left with a force of 4 N. Which of the following best describes the movement of the couch?
A) The couch will move to the left with a force of 1 N
B) The couch will not move
C) The couch will move to the right with a force of 7 N
D) The couch will move to the left with a force of 7 N
Is it A? Thanks!
yes
but I am sure you did not really need to ask :)
Thank you :D
I'm sorry if im too late for this question but the correct answer i think is
A) The couch will move to the left with a force of 1 N
yea
To determine the direction of movement of the couch, we need to consider the net force acting on it. The net force is the sum of all the individual forces acting on an object.
In this case, we have two forces acting on the couch: one to the right with a force of 3 N and the other to the left with a force of 4 N.
To find the net force, we need to subtract the force acting to the left from the force acting to the right:
Net force = force to the right - force to the left
Net force = 3 N - 4 N = -1 N
The negative sign indicates that the net force is in the direction opposite to the force you subtracted. In this case, since the net force is negative, it means the couch will move to the left.
However, the question asks for the force of the movement. The force of movement is not equal to the net force. The force of movement, also known as the resultant force, is the absolute value (without the negative sign) of the net force.
So, in this case, the force of movement is 1 N (the absolute value of -1 N).
Therefore, the correct answer is:
A) The couch will move to the left with a force of 1 N
