The range of a projectile is given by:
[tex]R=\frac{v^2_0\sin 2\theta}{g}[/tex]where v0 is the initial velocity, theta is the angle and g is the acceleration of gravity. Plugging the values given we have that:
[tex]\begin{gathered} R=\frac{(50)^2\sin (2\cdot40)}{9.8} \\ R=251.23 \end{gathered}[/tex]Therefore the range is 251.23 meters
