State Newton's Second Law of Motion in words and draw a labelled free-body diagram showing ALL the forces acting on block B.

Here are the solutions to Question 2:

2.1 State Newton's Second Law of Motion in words.

Newton's Second Law of Motion states that the net force acting on an object is directly proportional to the acceleration of the object, in the direction of the net force, and inversely proportional to the mass of the object.

2.2 Draw a labelled free-body diagram showing ALL the forces acting on block B.

For block B:

• $F_{app}$: Applied force (32 N) to the right.
• $T$: Tension force from the string to the left.
• $f_k$: Kinetic frictional force to the left.
• $F_g$: Gravitational force (weight) acting downwards.
