Solve the problem. Assume the x-axis is horizontal, the positive y-axis is vertical (opposite g), the ground is horizontal, and only the gravitational force acts on the objects. A projectile is launched from the origin at an angle of ? radians to the horizontal and an initial speed of 
Find the position function r(t) for this projectile.
A. r(t) = (125t cos ?)i + (125t sin ? - 16t2)j B. r(t) = (125t cos ? - 32t2)i + (125t sin ?)j C. r(t) = (125t sin ? - 16t2)i + (125t cos ?)j D. r(t) = (125t sin ?)i + (125t cos ? - 16t2)j
