The work is #=50.92J#

Resolving in the direction parallel to the plane #↗+#

As the component of the weight perpendicular to the plane do not perform work

#F=mgsintheta#

The mass is #m=2kg#

The angle is #theta=1/3pi#

#F=2gsin(1/3pi)=16.97N#

The distance is #d=3m#

The work is

#W=F*d=16.97*3=50.92J#
