Conserving the momentum, as there are no external forces. The total Y momentum of the body gets transferred to the inclined plane (As final momentum of the ball is only in X direction).
conserving the momentum in the direction perpendicular to the line of impact that is along inclined plane.
=> .   M*Vi *cos 60° = M*Vf* cos30°
=> .   3/2 = √3Vf/2 
=>.     Vf = √3 m/s
 
So Vx body = -1/√3
