Work done is 49 Joules.

Explanation:

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