#1

State which of the following situations are possible and give an example for each of these?
(i) An object with a constant acceleration but with zero velocity.
(ii) An object moving in a certain direction with acceleration in the perpendicular direction.


#2

Both the situations are possible
(i) When an object is projected upwards, its velocity at the top-most point is zero even though the acceleration on it 9.8 m/${{s}^{2}}$(g).
(ii) When a stone tied to a string is whirled in a circular path, the acceleration acting on it is always at right angles i.e. perpendicular to the direction of motion of stone (we will study about it in motion in a plane).
