Let h = (v o^2 / 4.9) sin theta cos theta model the horizontal distance in meters traveled by a projectile. If the initial velocity is 52 meters/second, which equation would you use to find the angle needed to travel 200 meters?
A. 551.84sin(2theta)=200
B. 275.92sin(2theta)=200
C. 10.61 sin(2theta)=100
D. 200 sin(2theta)=200

Best ResponseYou've already chosen the best response.1Then we get \[\large 200=\frac{52^{2}}{4.9}\times \frac{\sin 2\theta}{2}\]
