From the velocity-time graph, we can determine :

1. The displacement of the body in a certain time interval.
2. The acceleration of the body at any instance.
3. Both (a) and (b)
4. None of these

Velocity x time = :

1. Average velocity
2. Displacement
3. Acceleration
4. Speed

For a uniformly retarded motion, the velocity-time graph is:

1. a curve
2. a straight line parallel to the time axis
3. a straight line perpendicular to the time axis
4. a straight line inclined to the time axis.

Study the velocity-time graph shown below and answer the questions that follow:

(i) The distance travelled in 5s:

1. 10 m
2. 50 m
3. 125 m
4. 250 m

(ii) The retardation of the body as calculated from the graph is:

1. 12 ms^-2
2. 15 ms^-2
3. 10 ms^-2
4. 20 ms^-2
