Homework Help: physics

Posted by Mitch on Saturday, March 6, 2010 at 8:29pm.

ok so dr= 2i + 3j while F= 5i + 2j
It wants me to find the work. now i know w=Fxdr. what i want to know is why when you take the dot product of both, you get a different answer compared to when you just multiply the magnitudes.
