1. (12 points) (a) Draw the following two vectors on the paper, and add them graphically.
vector 3: 2.0 cm in the -y direction
vector b: 6.0 cm in the +X direction
(b) Using a ruler, measure the magnitude of the resultant vector c (=a+b)
(c) Using the Phythagorian theorem, calculate the magnitude of c and compare it with the
measurement
((1) What is the angle between the vector c and vector b? 2. (8 points) (a) Draw the following two vectors on the paper, and add them graphically.
