The velocity-time graph given below shows an object moving in a straight line. The displacement and the distance travelled by the object in 6 s will respectively be :

1. 8 m, 16 m
2. 16 m, 8 m
3. 16 m, 16 m
4. 8 m, 8 m

A rubber ball falls freely from a height h onto a smooth floor. After striking the floor, the ball again rises to the same height. Assume that the duration of contact of the ball with the floor is negligible. Identify the correct graph for velocity with time and height with time.
