In Problem 8, let a = 10° and find the magnitude of vector C using the component method.
In problem 8
Two vectors, each of magnitude 4.0 cm, are directed at a small angle a below the horizontal as shown. (The grid is 1 cm on a side.)
Let C = A + B. Sketch the direction of C and estimate its magnitude.
Let D = A - B. Sketch the direction of D and estimate its magnitude.
