A body of mass 10kg is placed on a smooth inclined plane making an angle of `30^(@)` with the horizontal, the component of the force of gravity trying to move the body down the inclined plane is `[g=9.8m//s^(2)]`

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.
