Randall D. Knight — Vectors and Coordinate Systems: Problem 11

Draw each of the following vectors, label an angle that specifies the vector’s direction, then find its magnitude and direction. a. \( \vec{B} = -4.0\hat{i} + 4.0\hat{j} \) b. \( \vec{r} = (-2.0\hat{i} - 1.0\hat{j}) \text{ cm} \) c. \( \vec{v} = (-10\hat{i} - 100\hat{j}) \text{ m/s} \) d. \( \vec{a} = (20\hat{i} + 10\hat{j}) \text{ m/s}^2 \)
