You might think about the graphs in terms of gradients.

You could consider replacing the vertical lines by very steep gradient lines.

To relate the problem to acceleration, recall that the acceleration is the second derivative of the position.

Don't forget that you are not allowed to have 'infinite' values on a graph.

This problem introduces the mathematics behind 'step functions' and 'Dirac delta' functions.
