Question

The $OA$ and $AB$ part of the graph correspond to

• A. uniform retardation, variable acceleration
• B. uniform acceleration, uniform velocity
• C. constant velocity, uniform acceleration
• D. uniform acceleration, varying velocity.

Answer 1

The correct option is B uniform acceleration, uniform velocity

Slope of region OA increases uniformly which results in uniform increase in velocity.
Thus, OA has a uniform acceleration.
Slope of AB remains constant.
Thus, there is a constant velocity in region AB.
