2N to the left
Explanation:
Given parameters:
Force of both boys = 3N + 6N = 9N
Net force = 7N
Unknown:
Frictional force = ?
Solution:
A body will remain in constant motion or a state of rest unless acted upon by an external force.
The net force is force that causes the motion of a body in the horizontal direction.
Net force = Force applied - Frictional force
frictional force always acts to impede the motion of a body.
input the values
7 = 9 - frictional force
-frictional force = 7-9
frictional force = 2N
Since frictional force opposes motion, it is directed to the left.
Without the force of friction that tends to impede motion, the net force and applied motion should be the same.
