Question
For an object undergoing constant acceleration, the average velocity for a trip can be calculated as the arithmetic mean of the initial and final velocities. This is valid provided the
Correct Answer
Option C is the correct answer.
Detailed Explanation
The formula v_avg = (v_i + v_f)/2 is derived from the equations of motion under the specific condition of constant acceleration. It is a direct consequence of the linear change of velocity with time.
Hint
This formula is a shortcut that comes from the set of equations that are valid only for a specific type of motion.
