OK instead of telling us what you don't know, it would actually be much more helpful if we could talk about what you DO know.What is it a graph of ? -- Impulse is (force applied) x (time the force persists). Is there force or time anywhere on the graph ?Is there acceleration anywhere on the graph, and do you know the mass ?With acceleration and mass, you could calculate the force.-- Impulse is also the change in momentum.Is there momentum anywhere on the graph ?Is there speed anywhere on the graph, and do you know the mass ? With speed and mass, you can calculate the momentum.We can use what you know to solve the problem. But we cannot use what you don't know to solve the problem.I just had the coolest idea: What if you took a picture of the Physics gragh that you're doing, and post it here along with your question ? ! Then we would have the same information that you have, and we could show you how to use it.
