Options

A. Average speed of a particle in a given time is never less than the magnitude of the avrage velocity
B. It is possible to have a situation in which `|(vec(dv))/(dt)|!=0` but `d/(dt)|vecv|=0`.
C. the average velocity of a particle is zero inn a time interval. It is possible that eh instantaneous velocity is never zero in the interval.
D. The average velocity of a particle moving on a straight line is zero in a time interval. It is possible that the instantaneous velocity is never zero in the interval. (Infinite accelerations are not allowed).
