4. The acceleration due to gravity in a 3D space is denoted as (0, 0, -9.8) mfsz. A shell is red from the point 0. An aircraft ying with a velocity of (150, 150, 0) m/s is at the point whose position vector is (-500, 500, 1510) m with respect to point 0 when the shell is red. If the altitude of the aircraft is maintained at 1510 m, and the ring angles in this question are denoted by 2 angles, namely (i) horizontal rotation angle in counter-clockwise direction from the xaxis of the artillery gun and (ii) elevation angle of the artillery gun in a vertical plane, fund the initial speed and the ring angles of the shell if it strikes the aircraft after 10 seconds. (3 00 ms, 9 =63.43, 6' =41.81) Rotation Elevation
