Limiting Friction and Block on Incline

Examples on Friction || Block on Incline Plane

The value of F at which no friction will act on block on inclined plane , is :

The ratio of acceleration of blocks A placed on smooth incline with block B placed on rough incline is 2:1 . The coefficient of kinetic friction between block B and incline is

A block of mass m lying on a rough horizontal surface of friction coefficient mu is pulled by a force F as shown , the limiting friction between the block and surface will be

A block of mass m is being pulled up the rough incline , inclined at angle theta with horizontal by an agent delivering constant power P. The coefficient of friction between block & incline is mu . Then during the upward motion along the inclined plane , maximum velocity of the block will be :

It takes a block twice as long to slide down a plane incline at 45^(@) to the horizontal as it would take for it to slide down the same plane had the plane been frictionless. Colculate the coefficient of friction between block and inclined plane.

A block is given certain upward velocity along the incline of elevation alpha . The time of ascent to upper point was found to be half the time of descent to initial point. The co-efficient of friction between block and incline is :

A block rests on a rough inclined plane making an angle of 30° with the horizontal. The coefficient of static friction between the block and inclined plane is 0.8. If the frictional force on the block is 10 N, the mass of the block is

An ice cube is kept on an inclined plane of angle 30^(@) . The coefficient to kinetic friction between the block and incline plane is 1//sqrt(3) . What is the acceleration of the block ?
