Asked by kristel
a 40-N forcee pulls a 4-kg a horizontal distance of 8 meterr. the rope makes an angle of 35 degree with the floor and the coefficient of kinetic friction is 0.2. what is the work done by each acting on block?

Ffloor = force on floor = ( m g - 40 sin 35)
Friction force = Ff = Ffloor*.2
work done against friction = Ff * 8
Horizontal force = 40 cos 35
Work done by Horizontal force = 40 cos 35 * 8
Friction force = Ff = Ffloor*.2
work done against friction = Ff * 8
Horizontal force = 40 cos 35
Work done by Horizontal force = 40 cos 35 * 8
