![4) A projectile is fired with an initial speed (v) of 175 m/s, at an angle a of 30 degrees, and
at a position 600 m above ground level. Based on Newton's 2nd Law and assuming no air
resistance, the position vector of the projectile is:
r(t) = (vecosa)ti + [ro+(vesina)t - 1/2gt²)]j
where time t≥ 0, ro is the initial height above ground surface, and the acceleration of
gravity g = 9.81 m/s².
