Find the firing angle in degrees of a projectile

Reference no: EM13178404

The altitude of a projectile in feet (neglecting air resistance) is given by: y=(tan*)x-16/(v^2 cos^2*)x^2: (y= (tangent of thada) times x minus 16 over (velocity squared cosine squared of thada) times x squared. [the astericks represent thada]

where x is the horizontal distance covered in feet and v is the initial velocity of the projectile at an agle thada from the horizontal. Find the firing angle in degrees of a projectile fired at an initial velocity of 100 feet per second so that it strikes the ground 312.5 feet from the firing point.
