I might be able to help
i took engineering for a year so i might be of help! ill try my best but if not i do apologize

see its about torque you know:
If we put 5 kg on right after removing 20kg then :
Torque =(perpendicular component of force vector ) X (distance from the axis )
for rotational equilibrium Torque should be balanced.
Now we calculate torque /
Answer:
B) a kinetic friction
Explanation:
The force of friction in a movement object its called kinetic friction force (<em>fk). </em>The net force acting in the direction of the movement its express, according to the Newton second law, like this: F- <em>fk. </em>That expression says that the net force produces an aceleration in the direction of the movement of the object.
Now if the force its removed, the <em>fk</em> its continue acting in the object but now in the opposite direction. And according to the Newton second law this <em>fk </em>it going to continue acting until the object stay in a still state.
<u>In conclusion</u>, if an object moves in some direction the kinetic friction force always be opposite to that direction of movement, according to the Newton second law
