$2.55 \ "J"$

We use the work equation, which states that,

$W=F*d*costheta$

$F$ is the force in newtons

$d$ is the distance moved in meters

$theta$ is the angle of incline

Therefore, the weight is: $1 \ "kg"*9.8 \ "m/s"^2=9.8 \ "N"$ .

And so, the work done is:

$W=9.8 \ "N"*1 \ "m"*cos((5pi)/12)$

$=9.8 \ "N"*0.26$

$~~2.55 \ "J"$
