A box of weight 220 N is being pulled to the right by a force \( F \) of magnitude 30 N. The coefficient of static friction between the box and the floor is 0.15.

To make an accurate free-body diagram of the box, the letter \( W \) in the diagram should be replaced with the label:

A) 220 N
B) 30 N
C) 0.15
D) \( F \)

Answer :

Final answer:

In a free-body diagram where 'W' represents the weight of an object, for a box with a weight of 220 N, 'W' should be replaced with label 'A) 220 N'.

Explanation:

To create an accurate free-body diagram of the box that is being pulled, the letter 'W' should be replaced with the label 220 N. In the context of physics and free-body diagrams, the letter 'W' typically represents the weight of the object, which in this case is the weight of the box given as 220 N. Hence, the correct label to replace 'W' would be option A) 220 N. However, in this scenario, the weight of the box is explicitly given as 220 N. So, in the accurate free-body diagram, the letter 'W' should be replaced with the label A) 220 N, as it represents the weight of the box. The other options (B) 30 N, (C) 0.15, and (D) F are not appropriate replacements for the weight in this context.
