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 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 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 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 small body of mass m is located on a horizontal plane at the point O. The body acquires a horizontal velocity v_0 . Find the mean power developed by the friction force during the whole time of motion, if the frictional coefficient mu=0.27 , m=1.0kg and v_0=1.5ms^-1 .

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

A block moving on a horizontal surface with velocity 20 ms^(-1) comes to rest because of surface friction over a distance of 40 m. Taking g = 10 ms^(-2) , the coefficient of dynamic friction is :

A block of mass 1 kg lies on a horizontal surface in a truck. The coefficient of static friction between the block and the surface is 0.6. If the acceleration of the truck is 5m//s^2 , the frictional force acting on the block is…………newtons.
