The following equation describes the horizontal range of a projectile, fired from a height of zero, at an angle of ?θ, with an initial velocity of v: ?= ?^2 sin(2?) / ?, where g is the acceleration of gravity. Use kinematics to derive this equation by assuming the magnitude of the initial velocity to be v.
