For a uniformly retarded motion, the velocity-time graph is:
- a curve
- a straight line parallel to the time axis
- a straight line perpendicular to the time axis
- a straight line inclined to the time axis.

Answer
a straight line inclined to the time axis
Reason — If the motion is uniformly retarded (i.e., its velocity decreases by an equal amount in each second), the velocity-time graph will be a straight line inclined to the time axis with a negative slope.

The velocity-time graph of a body in motion is a straight line inclined to the time axis. The correct statement is —
- velocity is uniform
- acceleration is uniform
- both velocity and acceleration are uniform
- neither velocity nor acceleration is uniform.
Study the velocity-time graph shown below and answer the questions that follow:
(i) The distance travelled in 5s:
- 10 m
- 50 m
- 125 m
- 250 m
(ii) The retardation of the body as calculated from the graph is:
- 12 ms-2
- 15 ms-2
- 10 ms-2
- 20 ms-2
The graph representing the state of rest of an object is :
