so anyways my science teacher mr mcfaddengave us this question for homeworkpredict what will happen if 30 pencils taped together and dropped at the same time with a single pencil . i get that in gravity he is trying to say which one will land first that is my question which 1 will land first

Didn't Galileo demonstrate that things fell at the same rate, independent of their masses?
