Physics - Kinematics Question with Solution | TestHub

The acceleration-displacement graph of a particle moving in x -direction is shown. If the initial speed of the particle is $\overrightarrow{\mathrm{u}}=-3\hat{\mathrm{i}}\mathrm{m}/\mathrm{s}$, the velocity of the particle at $\mathrm{s}=3\mathrm{m}$ is-
