Question

the block of wood is placed on a rough horizontal plane.if the friction between the block and the plane is 6n ,what is the work done to move the block througha distance of 1.5m?​

Answer 1

Gravitation for exert on block along slope = Mgsin30

Since net force is 0 (constant speed)

Frictional force = Mgsin30

C(friction) = Frictional Force/Normal Force

Normal Force = Mgcos30

C(friction) = Frictional Force/Normal Force

=Mgsin30/Mgcos30

= tan 30

=0.577
