If both $Assertion$ and $Reason$ are correct and the $Reason$ is a correct explanation of the $Assertion$.

Vedclass · Answer

(A) When a body is thrown vertically upwards,at the highest point,its velocity becomes $0 \ m/s$.However,the gravitational force continues to act on it,resulting in a constant downward acceleration of $g \approx 9.8 \ m/s^2$.Thus,a body can have acceleration even when its velocity is zero at a specific instant.Therefore,the $Assertion$ is correct.When a body reverses its direction of motion,it must momentarily come to rest (velocity becomes zero) before moving in the opposite direction.This change in velocity is caused by the acceleration acting on the body.Thus,the $Reason$ is correct and it provides a valid explanation for why the velocity can be zero while acceleration is non-zero.

Column $I$	Column $II$
$(A)$ Height of particle from ground	$(p)$ $0$
$(B)$ Speed of particle	$(q)$ $10$ $SI$ unit
$(C)$ Displacement of particle	$(r)$ $40$ $SI$ unit
$(D)$ Acceleration of particle	$(s)$ $20$ $SI$ unit

$Assertion$ : $A$ body can have acceleration even if its velocity is zero at a given instant of time.
$Reason$ : $A$ body is momentarily at rest when it reverses its direction.
