The solution for the given question is
1. Negative acceleration - The velocity of the object decreases - A vehicle moving with the velocity of 10 m/s, stops after 5 seconds.
2. Positive acceleration- The velocity of the object increases - A car, initially at rest reaches a velocity of 50 km/hr in 10 seconds.
3. Zero acceleration - The velocity of the object remains constant - A vehicle is moving with a velocity of 25 m/s
Note: Negative acceleration is also called retardation.
