The horizontal distance traveled by the projectile is given as
![d= \frac{V_{0}^{2}}{4.9} sin\theta cos\theta](https://tex.z-dn.net/?f=d%3D%20%5Cfrac%7BV_%7B0%7D%5E%7B2%7D%7D%7B4.9%7D%20sin%5Ctheta%20cos%5Ctheta)
where
V₀ = initial velocity, m/s
Note that
sin(2θ) = 2sinθ cosθ
Therefore, the horizontal distance traveled is
![d= \frac{V_{0}^{2}}{4.9} ( \frac{sin(2\theta)}{2} )= \frac{V_{0}^{2}}{9.8} sin(2\theta)](https://tex.z-dn.net/?f=d%3D%20%5Cfrac%7BV_%7B0%7D%5E%7B2%7D%7D%7B4.9%7D%20%28%20%5Cfrac%7Bsin%282%5Ctheta%29%7D%7B2%7D%20%29%3D%20%5Cfrac%7BV_%7B0%7D%5E%7B2%7D%7D%7B9.8%7D%20sin%282%5Ctheta%29)
Because V₀ = 52 m/s, in order to travel a horizontal distance of 200 m, the correct equation to determine θ is
(52²/9.8) sin(2θ) = 200
or
275.92 sin(2θ) = 200
Answer: A
Answer:
Step-by-step explanation:
<u>Given</u>
- Perpendicular line that passes through the point (-1, -2)
Perpendicular line has negative reciprocal slope, so the slope is -1
<u>The line in slope-intercept form is:</u>
<u>Using the given point, finding the y-intercept:</u>
- -2 = -(-1) + b
- -2 = 1 + b
- b = -2 - 1
- b = -3
<u>So the Werewolf's equation is:</u>
