A force is applied that makes an object move with the acceleration shown below. Assuming that friction is negligible, sketch a force-time graph of the force on the object on the axes below.

Since i don't have a scanner. Let me describe the graph of the acceleration. It oscillates from positive 1 to negative 1.5, then to positive two, then negative 1.5 then to positive 1 and evens out. So there are three humps within 5 seconds.

i don't know the relationship between the acceleration graph and force graph so i am stuck here. I know that they have to be in the same direction because 'a force [was] applied that made the object move'. But how will the graph of the force vs time look. Will it just be the derivative of the acceleration graph?
