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

The slope of displacement-time graph gives:

1. Velocity
2. Acceleration
3. Speed
4. Displacement

From the given displacement-time graph, answer the following questions:

(i) The kind of motion depicted in this graph is :

1. uniform
2. non-uniform
3. retardation
4. all of the above

(ii) The velocity between point A and C is:

1. 20 ms^-1
2. 5 ms^-1
3. 10 ms^-1
4. 15 ms^-1

(iii) The displacement at t = 3s is:

1. 15 m/s²
2. 12.5 m/s²
3. 40 m
4. 30 m
