5. Suppose a block slides horizontally across the floor. The acceleration of the block as a function of time is shown below: a (m/s) 4 2 -2 1 2 3 4 5 t (s) 6 Using * = 0 and = 0 at t = 0 plot the position and velocity v 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 = 6 s.
