| - Now that we know the angle, we can find our horizontal and vertical components of velocity by simply plugging $\theta$ into the two substitutions above: $v_x=50\cos(39.3°)=38.7$ m/s and $v_y=50\sin(39.3°)=31.6$ m/s. | - Now that we know the angle, we can find our horizontal and vertical components of velocity by simply plugging $\theta$ into the two substitutions above: $v_x=50\cos(39.3°)=38.7$ m/s and $v_y=50\sin(39.3°)=31.6$ m/s. | ||
| - The process for figuring out how to hit the second encampment 52 m above the first one is relatively similar, with two key differences. Firstly, we need to increase the sling-shot speed; at 50 m/s, no matter what angle you aim the bird, it will never reach the encampment. Increasing it to 75 m/s should be sufficient. Secondly, we need to adjust the $y$ in the system of equations from 0 to 52 to model the elevation difference between the two encampments. With these changes, we can follow the process detailed in part 1 & 2. We find that $\theta=25.4°$, $v_x=67.7$ m/s, and $v_y=32.2$ m/s. | - The process for figuring out how to hit the second encampment 52 m above the first one is relatively similar, with two key differences.
