A square platform of side length 8 m is situated in x-z plane such that it is at 16 m from the x-axis and 8 m from the z-axis as shown in figure. A particle is projected from origin with velocity →v=v2^i+25^j m/s relative to wind which is blowing with velocity v1^k. And at the same instant the platform starts with acceleration →a=2^i+2.5^j m/s2.
