Best ResponseYou've already chosen the best response.0\[R=\frac{u^2 \sin(2 \theta)}{g}\] \[\theta = 30 degrees\]R=120m \[120=\frac{u^2 \sin(2 *30)}{10}\] find u.

Best ResponseYou've already chosen the best response.0ok, so is it 170 m, 98 m , 140 m , 85 m or 150 m? trying to check my answer

Best ResponseYou've already chosen the best response.0\[u^2 = \frac{120*10}{\sin 60}\] \[u^2 = 800\sqrt{3}\] now theta = 45 \[R=\frac{u^2 \sin(2*45)}{10}\] substitute value of u^2. \[R=\frac{800 \sqrt{3} \sin(2*45)}{10}\]
