the figure on the right contains six free-body diagrams. which of the diagrams represent an object that has some acceleration in the vertical direction?
□ e
□ a
□ b
□ d
□ c
□ f

Explanation:

An object has vertical acceleration when the net vertical force is non-zero (unbalanced vertical forces).

• Diagram A: Only horizontal forces, vertical forces are absent (net vertical force = 0, no vertical acceleration).
• Diagram B: Only horizontal forces, vertical forces are absent (net vertical force = 0, no vertical acceleration).
• Diagram C: Unbalanced vertical forces (downward force > upward force, net vertical force ≠ 0, has vertical acceleration).
• Diagram D: Only horizontal forces, vertical forces are absent (net vertical force = 0, no vertical acceleration).
• Diagram E: Unbalanced vertical forces (vertical forces are unequal, net vertical force ≠ 0, has vertical acceleration).
• Diagram F: Only horizontal forces, vertical forces are absent (net vertical force = 0, no vertical acceleration).

Answer:

C. Diagram C, E. Diagram E
