The given graph has instantaneous acceleration and therefore equations of kinematics cannot be applied to it.
Similarly, the average acceleration between time t=0 and time t=2 is 1 m/s2 .
With average acceleration between time t=0 and time t=2 and from time t=2 to time t=4, we can now solve the equation of kinematics for finding the velocities at time t=2 and time t=4.
Now with all the average and uniform quantities, we can apply laws of kinematics for displacement
