A /DIS(m:2f)/DIS(kg_u) block situated on a rough incline (assume an angle of /DIS(alpha) = /DIS(angle:1f)/DIS(deg_u)) is connected to a spring of negligible mass having a spring constant k = of /DIS(k:0f)/DIS(NPm_u) (see the figure below)./DIS(newline)
/DIS(newline)/DIS(picture)
The block is released from rest when the spring is unstretched, and the pulley is frictionless. The block moves /DIS(d:1f)/DIS(cm_u) down the incline before coming to rest. Find the coefficient of kinetic friction between block and incline.
