How much work would it take to push a #8 kg # weight up a # 7 m # plane that is at an incline of # pi / 12 #?

1 Answer

Answer:

The work done to push the given weight is 142 Joules.

Explanation:

If a body of mass 'm' slides down on an inclined plane of inclination '#theta#' through a distance 'S', then work done by gravity is #W=(mgsintheta)S#.

By substituting the values we get,
#W=[8kgxx9.8m/s^2xxsin(pi/12)]xx7m#
#=>W=142.039~~142# Joules.
