\f4) (10 points) A projectile is fired with an initial speed (vo) of 175 m/s, at an angle a of 30 degrees, and at a position 600 m above ground level. Based on Newton's 2" Law and assuming no air resistance, the position vector of the projectile is: r(t) = (vocosa)ti + [ro+(vesina)t - 1/2gt?)]j where time t = 0, ry is the initial height above ground surface, and the acceleration of gravity g = 9.81 m/s?. Where does the projectile hit the ground and with what speed
