2D vectors, Magnitude & Direction/Components:
θA = 28.0°
A = Acosθ i - Asinθ j = 44.0cos28.0 i + 44.0sin28.0 j = 38.8 i + 20.7 j
2A = 2(38.8 i + 20.7 j) = 77.6 i + 41.4 j
θB = 180.0 - 56.0 = 124.0°
B = Bcosθ i - Bsinθ j = 26.5cos124.0 i + 26.5sin124.0 j = -14.8 i + 22.0 j
For the vectors shown in the figure, determine
Part A. the magnitude of 2A − 3B + 2C. Express your answer using three significant figures.
Part B. the direction of 2A − 3B + 2C. Express your answer using three significant figures.
