Option 1: This option is not relevant to the given question. It does not provide any information about the average velocity of the body.
Option 2: This option is also not relevant to the question. It does not provide any information about the average velocity of the body.
Option 3: This option is not relevant to the given question. It does not provide any information about the average velocity of the body.
Option 4: This option correctly states that the average velocity of the body is equal to the arithmetic mean of the initial and final velocities. According to the question, the body travels half the distance with velocity v and the next half with velocity v2. The average velocity in this case is given by:
Average Velocity = (v + v2) / 2
Therefore, option 4 is the correct answer, as it correctly describes the average velocity of the body in the given scenario.
Alert - correct answer should be "Option 4"
