Question-4) [Total 20 points] A thin light string is wrapped around a solid uniform disk of mass M and radius r, mounted as shown. The loose end of the string is attached to a block of mass m which is allowed to slide down an inclined plane that makes angle 0 with the horizontal. M,r (Part a) [5 points] Draw free body diagram for the block of mass m in the case i) there is no friction and ii) there is a friction between the block and the inclined plane with kinetic friction constant Uk. (Part b) [15 points] Find the acceleration a of the block of mass m in the case i) there is no friction and ii) there is a friction between the block and the inclined plane with kinetic friction constant Uk.
