The vector A has a magnitude of 5mph and points along the x-axis, vector B has a magnitude of 8mph and makes an angle of 150 degrees, and vector C has a magnitude of 10mph and an angle of 255 degrees. The unit stands for miles per hour.
1. Find the total vector, T = A + B + C, graphically by tracing the arrows on paper and drawing the total vector. Measure the magnitude and total vector w/ruler and protractor.
2. Compute the addition mathematically in terms of magnitudes and directions of the components.
3. Is the graphical total vector consistent w/the calculated T?
4. Repeat for the vector R = A - B - C both graphically and mathematically
