Part A Write the vector , in (Figure 1) in terms of the unit vectors î and Î. Express your answer in terms of the unit vectors i and Ĵ. Use the 'unit vector button to denote unit vectors in your answer. Express the coefficients in meters. A = 1.23i +3.38j m Submit Previous Answers ✓ Correct IDENTIFY: Use trigonometry to find the components of each vector. Use R = A + B +... and Ry = Ay+By+... to find the components of the vector sum. The equation Ā= Axi + Ayj expresses a vector in terms of its components. SET UP: Use the coordinates in the figure that accompanies the problem. EXECUTE: Ā= (3.60 m) cos 70.0°î + (3.60 m) sin 70.0°9 = (1.23 m)i + (3.38 m)ị Part B Write the vector B in the figure in terms of the unit vectors i and j. Express your answer in terms of the unit vectors i and ġ. Use the 'unit vector' button to denote unit vectors in your answer. Express the coefficients in meters. B = -2.07î - 1.2 m Submit Previous Answers Correct B=-(2.40 m) cos 30.0°î– (2.40 m) sin 30.0°)= (-2.08 m)i + (-1.20 m)ſ Part C Use unit vectors to express the vector C, where C = 3.00A - 4.00B.
