A)at the beginning of the time interval.
B)at the end of the time interval.
C)half-way through the time interval.
D)three-fourths of the way through the time interval.

Quizplus · Accepted Answer

When acceleration is constant, the average velocity is equal to the instantaneous velocity at the midpoint of the time interval. This is because, in uniform acceleration, the velocity changes linearly over time, making the average velocity (initial velocity + final velocity)/2 equal to the instantaneous velocity at the midpoint.

In the Case of Constant Acceleration,the Average Velocity Equals the Instantaneous
