For this problem, use standard conventions for directions (i.e., treat motion that is UP as positive and RIGHT as positive). The vector \vec{A} has a magnitude of 10 and is traveling at an angle of 40° to the right of the positive y-axis. Vector \vec{B} has a magnitude of 2 and is traveling at an angle 20° above the positive x-axis. Vector \vec{C} is described by the equation 2.0\hat{i} + 3.0\hat{j} - 5.0\hat{k}. a) Draw vectors \vec{A} and \vec{B} in an appropriate coordinate plane. b) Write vectors \vec{A} and \vec{B} using standard unit vector notation. c) Solve the following using analytical methods. You must show your work and manually solve these WITHOUT using matrix methods provided by your calculator: i) \vec{A} + \vec{B} + \vec{C} ii) \vec{A} \cdot \vec{B} iii) \vec{C} \times \vec{B}
