5005 Praxis Practice Test Practice Question
In which of the following situations will a ball experience the greatest acceleration?
Correct Answer: D
Rationale: To determine acceleration, Newton's second law (F=ma) applies, where acceleration (a) equals force (F) divided by mass (m).
Option D applies a 200 Newton force to a 50 g ball (0.05 kg), resulting in an acceleration of 4000 m/s².
In contrast, Option A (100 N on 0.1 kg) yields 1000 m/s², Option B (100 N on 175 kg) results in 0.57 m/s², and Option C (200 N on 0.25 kg) provides 800 m/s².
Thus, D experiences the greatest acceleration due to the combination of a high force and a low mass, while the other options either have higher mass or lower force, resulting in lower accelerations.
