Step 1
5 m and vector B has a magnitude of 3.1 m, we can calculate the magnitude of the resultant vector R using the formula: \[ R = \sqrt{(4.5)^2 + (3.1)^2} \] \[ R = \sqrt{20.25 + 9.61} \] \[ R = \sqrt{29.86} \] \[ R \approx 5.46 \, m \] Show more…

Vector A has a magnitude of 25 units and points due East, while vector B has the same magnitude and points due South. Find the direction and magnitude due East of: a.) A + B = R (resultant) b.) A - B = D (difference) Two forces, A and B, act at a point. A is 8N at 60 degrees above the +x-axis in the first quadrant, and B is 6N at 47 degrees below the +x-axis in the fourth quadrant. What are the magnitude and direction (from the +x-axis) of the resultant, R?

SECTION 3.1 VECTORS AND THEIR PROPERTIES 1. Vector A has a magnitude of 29 units and points in the positive y-direction. When vector B is added to A, the resultant vector A + B points in the negative y-direction with a magnitude of 14 units. Find the magnitude and direction of B. 2. Vector A has a magnitude of 8.00 units and makes an angle of 45.0° with the positive x-axis. Vector B also has a magnitude of 8.00 units and is directed along the negative x-axis. Using graphical methods, find (a) the vector sum A + B and (b) the vector difference A – B.

Vector $A$ has magnitude $8.00 \mathrm{~m}$ and is in the $x y$ -plane at an angle of $127^{\circ}$ counterclockwise from the $+x$ -axis $\left(37^{\circ}\right.$ past the $+y$ -axis). What are the magnitude and direction of vector $\vec{B}$ if the $\operatorname{sum} \vec{A}+\vec{B}$ is in the $-y$ -direction and has magnitude $12.0 \mathrm{~m} ?$
