Weight=mg=49*9.8N
Acting along just downward

shamim · Answer

Component of weight along inclined surface is=
49*9.8*sin34

shamim · Answer

Component of weight  perpendicular to the inclined plane is=49*9.8*cos34

shamim · Answer

Static frictional force=coefficient of static friction*R=0.73*49*9.8*cos34=?
