A body of mass M starts sliding down on the inclined plane where the critical angle is `angleACB=30^(@)` as shown in figure. The coefficient of kinetic friction will be

A block of mass m sliding down an inclined at constant speed is initial at a height h shown the ground as shown in the figure above . The coefficient of kinetic friction between the mass and the inclined is mu . If the mass constinues to slide down the inclined at a constant speed how much energy is displaced by friction by the time the mass reaches the bottom of the incline?

A block slides down an incline of angle 30^(@) with an acceleration of g//4 Find the coefficient of kinetic friction .

A body is sliding down an inclined plane forming an angle 30^(@) with the horizantal. If the coefficient of friction is 0.3 then acceleration of the body is
