Solution

The correct option is C Statement-1 is True; Statement-2 is False.
On a curved path, distance > displacement
Average speed>average velocity
Further, Average velocity =Total displacementTotal time
In case of curved path, since the initial and final velocities are vectors in different directions and acceleration is not constant so we cannot say that the average velocity is the mean of initial velocity and final velocity i.e Vav v1+v22. It is only true when motion is in straight line and accleration is constant.
