Friction On Horizontal Surafce |Part 2

Figure shows an irregular wedge of mass m placed on a smooth horizontal surface. Part BC is rough. If the coefficient of friction between the block and wedge is mu , and the block comes to rest with respect to wedge at a point E on the rough surface then BE will be

A horizontal force of 129.4 N is applied on a 10 kg block which rests on a horizontal surface. If the coefficient of friction is 0.3, the acceleration should be

A block of mass 2 kg rests on a horizontal surface. If a horizontal force of 5 N is applied on the block, the frictional force on it is ("take", u_(k)=0.4, mu_(s)=0.5)

A horizontal force of 1.2kg is applied on a 1.5kg block, which rests on a horizontal surface If the coefficient of friction is 0.3 find the acceleration produced in the block.

A horizontal force of 1 N is needed to keep a block of mass 0.25 kg sliding on a horizontal surface with a constant speed. The coefficient of sliding friction must be : [take g = 10 ms^(–2) ]

A heavy box of mass 20 kg is pulled on a horizontal force.If the coefficient of kinetic friction between the box and the horizontal surface is 0.25, find the force of friction exerted by horizontal surface on the box.

A body of mass 2kg is placed on a horizontal surface having kinetic friction 0.4 and static friction 0.5 . If the force applied on the body is 2.5N , then the frictional force acting on the body will be

A block of mass 1kg is at rest on a rough horizontal surface having coefficient of static friction 0.2 and kinetic friciton 0.15, find the frictional forces if a horizontal force, (a) F=1N (b) F=1.96N (c) F=2.5N is applied on a block
