2) [20] a block of wood is projected up an inclined plane with initial speed vo. if the inclination angle of the plane is 30° (measured from the horizontal) and the coefficient of sliding friction is k, find the total time needed for the block to return to its initial position. (the magnitude of the frictional force is equal to the component of force perpendicular to the surface multiplied by the coefficient of friction.)
