Calculus

A projectile is launched at an angle of 60 degrees to the horizontal from 6.5 ft above the ground at an initial speed of 150ft/sec. 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 object.

Find the velocity and position vectors for t ≥ 0?
ie. The velocity vector is v(t) = <__,__>
