A <display>&format(${m},'2f')</display><display>${kg_u}</display> bloke situated on a rough incline (assume an angle of <display>${alpha}</display> = <display>&format(${angle},'1f')</display><display>${deg_u}</display>) is connected to a spring of negligible mass having a spring constant k = of <display>&format(${k},'0f')</display><display>${NPm_u}</display> (see the figure below).<display>${newline}</display>

The bloke is released from rest when the spring is unstretched, and the pulley is frictionless. The bloke moves <display>&format(${d},'1f')</display><display>${cm_u}</display> down the incline before coming to rest. Find the coefficient of kinetic friction between bloke and incline.
