 There is no such case.
 
1 An object with a constant acceleration but zero velocity is not possible, because according to the definition of acceleration, acceleration is the rate of change in velocity. If an object is at zero velocity it does mean that it is at rest. So there is no change in velocity, hence no acceleration.

2 This case is possible. It is seen in circular motion

Anonymous: welcome
amritaSN04: AtharvaShetty thanks for the answer but the first case is possible. That's what my teacher said. but before, Even I was with your view of point.... anyway it is possible
Anonymous: no it is not
Anonymous: as a is derivative of velocity
amritaSN04: eg: when we throw a ball vertically upwards, when it reaches the top-most point the v=0 and the acceleration is not=0 due to gravity... I don't understand this example, that's why I asked you
Anonymous: hence constant acceleration should be 0
Anonymous: at top point velocity is 0
Anonymous: hence acceleration is still 9.8 and velocity changes to 0
amritaSN04: thanks
