Physics-General

- The body travels with constant speed upto time and then stops
- Instantaneous velocity
- Velocity of the body is continuously changing
- Constant velocity

#### Answer:The correct answer is: The body travels with constant speed upto time and then stopsUp to time slope of the graph is constant and after slope is zero the body travel with constant speed up to time and then stops
