Answer:

Work done is 49 Joules.

Explanation:

If a body of mass 'm' slides down on a smooth inclined plane of inclination '#theta#' through a distance 'S' work done by gravity to push body is
#W=(mg sintheta)S#
Considering acceleration due to gravity #g=9.8m//s^2# and substituting the given values in above equations we get,
#W=[((5kg)(9.8m//s^2)(sin(pi/6))][2m]#
#:.#work done #W=49#Joules.
