The time taken by a body to slide down a rough `45^(@)` inclined plane is twice that required to slide down a smooth `45^(@)` inclined plane. The coefficient of kinetic friction between the object and rough plane is given by

A given object takes n times as much time to slido down a 45^(@) rough inclined plane as it takes to slide down a perfectly smooth 45^(@) inclined plane. The coefficient of kinetic friction between the object and the inclined plane is given by:

A given object taken double time to slide down a 45^(@) rough incline as it takes to slide down a perfectly smooth 45^(@) incline. The coefficient of kinetic friction between the object and the incline is given by

An object takes n times as much time as to slide down a 45^(@) rough inclined plane it takes to slide down a perfectly smooth inclined plane of the same inslination. The coefficient of kinetic friction between the object and the rough inclied is given by

A given object taken n time more time to slide down 45^(@) rough inclined plane as it taken to slide down a perfectly smooth 45^(@) incline The coefficient of kintic friction between the object and the incline is .

A given object taken n time more time to slide down 45^(@) rough inclined plane as it taken to slide down a perfectly smooth 45^(@) incline The coefficient of kintic friction between the object and the incline is .

A given object takes n times as much time to slide down a 45^(@) rough incline as it takes to slide down a perfectly smooth 45^(@) incline. The coefficeint of kinetic friction between the object and the incline is given by:
