Given information
We are given that:-
Mass of box , .
The coefficient of static friction, .
The coefficient of kinetic friction, .
Step-by-step explanation
Step 1.
Boxes and are connected by a rope passing over a pulley. Box is lying on a table and box is hanging freely. According to Newton's third law of motion, the mass of box acts vertically down and the normal force acts vertically upwards. Since box is connected to box , it experiences a tension force along the length of the rope.
Box is hanging freely. Its weight acts vertically downwards and since the same rope passes over the pulley that connects boxes and , the same tension force acts on box B along the length of the rope. The forces acting are shown in the figure below:
