alleryTo find instantaneous velocity numerically, average velocity is calculated as the interval becomes:
ASteadier and steadier
BSharper and sharper
CSimpler and simpler
DSmaller and smaller
Answer & Solution
Correct answer: D. Smaller and smaller
1. The numerical method mirrors the limit in the definition.
2. Successive intervals must shrink towards the instant.
3. We plot the position time graph and calculate average velocity as the interval becomes smaller and smaller.
4. So the answer is smaller and smaller.
