. A particle is projected up along a rough inclined plane of inclination `45^(@)` with the horizontal. If the coefficient of friction is 0.5, the acceleration is

A body is projected up along a rough inclined plane of inclination 45 ^@ . The coefficient of friction is 0.5. Then the retardation of the block is

A particle is projected along the line of greatest slope up a rough inclined plane at an angle of 45^(@) with the horizontal. If the coefficient of friction is (1)/(2) then the retardation is :
