Question

claudia throws a baseball to her dog. which free - body diagram shows the baseball when its flying horizontally in midair? (assume no air resistance.)

Explanation:

Step1: Analyze forces on baseball

When in mid - air (assuming no air resistance), the only force acting on the baseball is its weight \(w\) (force due to gravity) acting vertically downwards.

Step2: Check each diagram

• Diagram A: Has an extra normal force \(F_N\) which is incorrect as there is no surface in contact to exert a normal force.
• Diagram B: Only shows the weight \(w\) acting downwards. This is correct as per the force analysis.
• Diagram C: The direction of forces is wrong (normal force concept misapplied as no surface contact).
• Diagram D: Direction of weight is wrong (weight acts downwards, not upwards).

Answer:

B. B
