The $x$ component of vector $\vec{A}$ is $-25.0 \mathrm{~m}$ and the $y$ component is $+40.0 \mathrm{~m}$. (a) What is the magnitude of $\vec{A} ?$ (b) What is the angle between the direction of $\vec{A}$ and the positive direction of $x ?$
SSM What are (a) the $x$ component and $(b)$ the $y$ component of a vector $\vec{a}$ in the $x y$ plane if its direction is $250^{\circ}$ counterclockwise from the positive direction of the $x$ axis and its magnitude is 7.3 $\mathrm{m} ?$
