Answer

$Range, R \approx 1223.36 \ ft$ $Height, H \approx 364.49 \ ft$

Work Step by Step

We compute the range and height using the given formulas as follows: Plug in $50^\circ$ for $\theta$ and $200$ for $v_o$ to obtain: $Range, R = \dfrac{v_0^2\sin{(2\theta)}}{g}=\dfrac{(200)^2\sin{(2 \times 50^\circ)}}{32.2} \approx 1223.36 \ ft$ $Height, H=\dfrac{v_0^2\sin^2{(\theta)}}{2g}=\dfrac{(200)^2\sin^2{(50^\circ)}}{2 \times 32.2} \approx 364.49 \ ft$
