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

. 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
