A body takes just twice the time as long to slide down a plane inclined at `30^(@)` to the horizontal as if the plane were frictionless. The coefficient of friction between the body and the plane is

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 body of mass 2 kg is placed on rough horizontal plane. The coefficient of friction between body and plane is 0.2 Then,

Starting from rest , a body slides down at 45^(@) inclined plane in twice the time it takes to slide down the same distance in the absence of friction. The coefficient of friction between the body and the inclined plane is

A body takes n times as much time to slide down a 45^@ rough incline as it takes to slide down a smooth 45^@ incline. The coefficient of friction between the body and the incline will be

A partical of mass 1kg rests on rought contact with a plane inclined at 30^(@) to the horizontal and is just about to slip, Find the coefficient of friction between the plane and the particle.

A piece of ics slides down a 45^(@) incline in twice the time it takes to slide down a frictionless 45^(@) incline . What is the coefficient of friction between the ice and the incline ? .

A body of mass 5xx10^(-3) kg is launched upon a rough inclined plane making an angle of 30^(@) with the horizontal. Obtain the coefficient of friction between the body and the plane if the time of ascent is half of the time of descent.

A block is at rest at the top of a rough inclined plane of inclination 30° with the horizontal. What is the coefficient of kinetic friction between the block and the plane, if the . block slides down with an acceleration of g/5 ?
