Suppose a block slides horizontally across the floor. The acceleration of the block as a function of time is shown below:

Using $x=0$ and $v_x=0$ at $t=0$ plot the position $x$ and velocity $v_x$ as functions of time. Your plots, especially the

position plot, do not need to be perfect $($although making the velocity plot quantitatively accurate is not too hard$)$; a

sketch is fine. But make sure to calculate and label on your plots the position and velocity at $t=4s$ and $t=6s.$
