How much work would it take to push a 4 kg weight up a 1 m plane that is at an incline of pi / 4 ?

Here work will be done against the component of force of gravity acting on the weight downwards along the plane.

So,for moving the weight with constant velocity,we just need to supply that amount of external force i.e mg sin ((pi)/4)=27.72N

So,work done in causing displacement by 1m would be W=F.s=27.72×1=27.72J
