A particle moves with a speed of $12\text{ m/s}$ directed at an angle of $30^{\circ}$ above the horizontal, as shown above. A line drawn from point $P$ to the particle is $3.5\text{ m}$ long and makes an angle of $50^{\circ}$ with the horizontal.

What is the angular momentum of the particle with respect to point $P$?

A

$7.3 \text{ kg}\cdot \text{m}^2/\text{s}$

B

$14\text{ kg}\cdot \text{m}^2/\text{s}$

C

$39\text{ kg}\cdot \text{m}^2/\text{s}$

D

$41\text{ kg}\cdot \text{m}^2/\text{s}$

E

$42\text{ kg}\cdot \text{m}^2/\text{s}$
