A small block of mass m=1kg is pulled slowly by applying a tangential force along a quarter circular arc of radius R = 0.1

A small block of mass m=1kg is pulled slowly by applying a tangential force along a quarter circular arc of radius R = 0.1 m from (0,0) to (R, R). The coefficient of friction varies in x- y plane asu (x) =. The modulus of work done by the frictional force on the block is y J. then y= (RRI
