To calculate the average velocity, we need to determine the total displacement of the body and the total time taken. The average velocity is defined as the total displacement divided by the total time.
Let's assume the initial velocity of the body is 15 m/s, and after some time, it reaches a final velocity of 100 m/s.
We know that: Initial velocity (u) = 15 m/s Final velocity (v) = 100 m/s
Since we don't have information about the time taken or the acceleration, we cannot directly calculate the total displacement. However, we can calculate the average velocity based on the given information.
Average velocity (v_avg) = (u + v) / 2
Substituting the values: v_avg = (15 m/s + 100 m/s) / 2
v_avg = 115 m/s / 2
v_avg = 57.5 m/s
Therefore, the average velocity of the body is 57.5 m/s.
