The range of a projectile that is launched with an initial velocity v at an angle of with the horizontal given by R=v^2/g
sin 2 theta
where g is the acceleration due to gravity or 9.8 meters per second squared. If a projectile is launched with an initial
velocity of 13 meters per second, what angle is required to achieve a range of 15 meters?
