Vectors 1.3 Part 2

Unit vectors are important in physics but not important yet in our stage of learning in physics. So if you want some really good information, go to http://www.youtube.com/watch?v=lQn7fksaDq0. Khan Academy provides this information. Listen if you have any questions that I have not covered please go to this Youtube site or his site khanacademy.com.

Now we have reached the end of chapter 1. This is our first chapter of our venture in physics. But before we move onto Chapter 2, we are going to try and solve a problem dealing with vectors. I will provide the answer tomorrow. Again please email me or go to khanacademy.com for further questions and answers.

Vector and Vector Addition

1) Hearing rattles from a snake, you make two rapid displacements of magnitude 1.8m and 2.4m. In sketches roughly to scale, show how your two displacements might add up to give a resultant of magnitude (a) 4.2m (b) 0.6m (c) 3.0m
