Momentum Vector#

A momentum vector expressed in component form is exactly $p_x=$ -7 $\mathrm{k}\mathrm{g}\mathrm{m}/\mathrm{s}$ and $p_y=$ -24 $\mathrm{k}\mathrm{g}\mathrm{m}/\mathrm{s}$.

Part 1#

The magnitude, $p$, and angle, $\theta$, measured counterclockwise with respect to the positive $x$-axis of this vector are:

Answer Section#

• $p=25\mathrm{k}\mathrm{g}\mathrm{m}/\mathrm{s}$, $\theta ={106.26}^{\circ }$.

• $p=-25\mathrm{k}\mathrm{g}\mathrm{m}/\mathrm{s}$, $\theta ={253.74}^{\circ }$.

• $p=25\mathrm{k}\mathrm{g}\mathrm{m}/\mathrm{s}$, $\theta ={73.74}^{\circ }$.

• $p=-25\mathrm{k}\mathrm{g}\mathrm{m}/\mathrm{s}$, $\theta ={73.74}^{\circ }$.

• $p=25\mathrm{k}\mathrm{g}\mathrm{m}/\mathrm{s}$, $\theta ={253.74}^{\circ }$.
