A helicopter is moving verticallly upwards with a velocity `5 ms^-1`. When the helicopter is at a height `10 m` from ground, a stone is thrown with a velocity `(3 hat i + 4 hat j) m s^-1` from the helicopter w.r.t. the man in it. Considering the point on ground vertically below the helicopter as the origin of coordinates, and the ground below as `xy` plane, find the coordinates of the point where the stone will fall, its distance from origin at the instant the stone strikes the ground, assuming helicopter moves upwards with constant velocity.
