If a particle moves with constant acceleration starting from rest, which statement is true regarding instantaneous velocity and average velocity over the interval from 0 to t?

If a particle moves with constant acceleration starting from rest, which statement is true regarding instantaneous velocity and average velocity over the interval from 0 to t?

• A. Instantaneous velocity equals the final velocity, and average velocity equals half of the final velocity.
• B. Instantaneous velocity equals the current velocity at time t; average velocity equals displacement divided by the total time.
• C. Instantaneous velocity is the slope of the distance-time graph.
• D. Average velocity equals twice the instantaneous velocity.

Answer: (B)
