In this problem, we would like to have the velocity of the point whose position vector is (r = 2î+3j-4k.) along the axis of vector (î-2j+2k).
Vpoint = Vcm + r sin@ w (where, angle @ is in between position vector and vector î-2j+2k )..
Actually, Vcm is zero, because no rolling but only rotation.
Also, the in the relation (v = r w), r should be in tangential direction with velocity vector.
Proceed, in this way and calculate the answer...
Good Luck….….…..
