Following are four different relation about displacement,velocity and acceleration for the motion of a particle in general.Choose the incorrect one (S). a) V_(av)=(1)/(2)[v(t_(1))+v(t_(2))] b) V_(av)=(r(t_(2))-r(t_(2)))/(t_(2)-t_(1)) c)r= (1)/(2)(v(t_(2))-v(t_(1))(t_(2)-t_(1)) d) a_(av)=(v(t_(2))-v(t_(1)))/(t_(2)-t_(1))

For any arbitrary motion in space, which of the following relations are true? a) v_("average") = (1//2)(v(t_(1) + v(t_(2)) b) v_("average") = [r(t_(2))-r(t_(1)]/(t_(2)-t_(1) v(t) = v(0) + at d) a_("average") = [v(t_(2))-v(t_(1))/[t_(2)-t_(1)) The average stands for average of the quantity over time interval t_(1) to t_(2)
