Look at the given velocity-time graph. Describe the motion of the object in each segment (OA, AB, BC).

Segment OA: The velocity-time graph is a straight line passing through the origin with a positive slope. This indicates that the object is moving with uniform positive acceleration, starting from rest.
Segment AB: The velocity-time graph is a straight line parallel to the time axis. This indicates that the object is moving with a constant velocity (uniform velocity), meaning its acceleration is zero.
Segment BC: The velocity-time graph is a straight line with a negative slope, ending at zero velocity. This indicates that the object is moving with uniform negative acceleration (deceleration or retardation) and eventually comes to rest.
