# How much work would it take to push a  5 kg  weight up a  2 m  plane that is at an incline of  pi / 6 ?

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
$W = \left(m g \sin \theta\right) S$
Considering acceleration due to gravity $g = 9.8 m / {s}^{2}$ and substituting the given values in above equations we get,
W=[((5kg)(9.8m//s^2)(sin(pi/6))][2m]
$\therefore$work done $W = 49$Joules.
