1. Let's clarify the problem: You mentioned calculating $F_y$, which typically refers to the vertical component of a force vector $\vec{F}$. 2. The formula to find the vertical component $F_y$ of a force $F$ acting at an angle $\theta$ from the horizontal is: $$F_y = F \sin(\theta)$$ 3. Important rules: - The sine function relates the angle to the opposite side in a right triangle, which corresponds to the vertical component here. - Make sure the angle $\theta$ is measured from the horizontal axis. 4. To calculate $F_y$, you need the magnitude of the force $F$ and the angle $\theta$. 5. Example: If $F = 10$ and $\theta = 30^\circ$, then $$F_y = 10 \times \sin(30^\circ) = 10 \times 0.5 = 5$$ 6. This means the vertical component of the force is 5 units. 7. If you provide the values of $F$ and $\theta$, I can help calculate $F_y$ explicitly.
