1) Negative acceleration, but positive velocity
If a ball is thrown up then velocity is positive upwards while acceleration is downwards negative
2) Positive acceleration and positive velocity
If a car is moving towards positive direction with increasing speed due to which acceleration is also positive in it
3) Positive acceleration, but negative velocity
If a car is moving towards negative direction and car apply brakes due to which it will slow down then its acceleration must be positive
4) Negative acceleration and negative velocity
When a ball is falling downwards under the influence of gravity then velocity and acceleration both are positive
5) Positive velocity and no acceleration
If an object is moving with uniform speed towards Positive X direction without any acceleration or force
