Problem
Under which one of the following conditions can the three equations of motion be applied without modification?
(a) When the magnitude of acceleration is constant but its direction keeps changing
(b) Only when the acceleration of the body remains constant in magnitude and direction
(c) When the acceleration acts along the same line but its magnitude changes uniformly with time
(d) Only if the object starts from rest, irrespective of how its acceleration varies later
