Consider the following st graph. What conclutions can be drawn regarding the velocity of the particle.

Explanation

`O` to `A`: Slope is +ve and increasing, i.e. velocity is +ve and increasing.
`A` to `B`: Slope is +ve and constant, i.e. velocity is +ve and constant.
`B` to `C`: Slope is +ve and decreasing, i.e. velocity is +ve and decreasing.
