Negative Forces?

rockinaway posted a topic in Homework Help

Is it possible to have negative forces? For example I have a question: The impact between the head and the dashboard lasts 0.008s Calculate the impact force between the head and the dashboard. So I do F = (mv-mu)/t = -112/0.008 Now I get the answer -14,000N... In am exam would I write -14,000N or just 14,000N?
