23.2 A plane is pointed in the positive x direction and is flying with an speed of (200, 0, 0) m/s relative to the air. However, due to an exceptionally strong updraft, the air is moving in the positive z direction at 50.0 m/s with respect to the ground. Find the velocity of the plane with respect to the ground.show your work

Response Details:
   Speed of plane relative to air   vp   =   (200, 0, 0)   =   200 i^   +   0 j^   +   0 k^
   Speed of wind relative to ground   vw   =   (0, 0, 50)   =   0 i^   +   0 j^   +   50 k^
   i^   =   unit vector along X axis, j^   =   unit vecor along Y axis,   k^   =   Unit vector along Z axis
   Speed of plane relative to ground      v   =   vp   +   vg
   v   =   200 i^   +   0 j^   +   50 k^
