Assertion : A body is momentarily at rest at the instant it reverses the direction.
Reason : A body cannot have acceleration if its velocity is zero at a given instant of time.

(A): A body is momentarily at rest at the instant it reverses the direction. (R): A body cannot have acceleration if its velocity is zero at a given instant of time.

Assertion : A particle may be momentarily at rest and yet have non-zero acceleration. Reason : The zero velocity of a particle at any instant does not necessarily imply zero acceleration at that instant.
