An ant on a picnic table travels 20 cm eastward then 25 cm northward 5 cm westward and finally 10 cm northward what is the ants displacement relative to its original position
turn it into a triangle pretty much. total displacement eastward is 15cm. total displacement northward is 35cm. now use the Pythagorean theorem which will be squareroot of 15squared+35squared. this gives you 38.08cm northeastward.
