I have been igned a physics ignment that i believe is way beyond my level and i need help.?

It is almost impossible for any one of us to know if you are advanced enough or not to work on a project like this. None of us know you or your school system. Generally, if your teacher igns something, then it is something that you can handle. Challenge you, yes, that is the teacher's job, but beyond your limits---only You can control that.
