Step 1- Drawing the FBD of the block and mentioning the forces acting on it ( friction and gravitational)
Step
2- for part a) the unbalanced force acting on the block down the
slide is gravitational force therefore
Step 3- For part b the net force is given by the gravitational fircr- friction force which is equated to mass of block x net acceleration
