Final answer:
The final velocity in the equation with average acceleration is equal to the initial velocity plus the product of the average acceleration and the time interval.
Step-by-step explanation:
In the equation for final velocity with average acceleration, the final velocity (V) is equal to the initial velocity (Vo) plus the product of the average acceleration (a) and time interval (t). This is captured by the formula V = Vo + at, where V represents the final velocity, Vo is the initial velocity, a is the acceleration, and t is the time over which the acceleration occurs.
When acceleration is constant, the average velocity during the time interval can be calculated as the simple average of the initial and final velocities, which is expressed as υ = (Vo + V) / 2. For example, if a car increases its velocity from 30 km/h to 60 km/h with constant acceleration, the average velocity during this time is 45 km/h, which is the simple average of the initial and final velocities.
