2. A disk of radius R and mass m is rollingdown an inclined plane at an angle a. Thecoefficient of static friction between theRinclined plane and the disk is µs. The diskrolls without slipping if Hs becomessufficiently high; however, the disk willbegin to slip for µs below a certain threshold.(a) Assuming that there is no slipping, listdown the Lagrangian equations of motion. Include the constraint forces atthe point of contact and use the coordinate axis indicated on the figure onthe right. (b) What is the value of us at which the disk would begin to slip?

Given that:radius of disk=Rangle of inclination=αfrictonal coefficient= μs
