A block of mass m 6 kg slides down a rough inclined plane, starting from rest. The elevation angle of the plane is 60 and the static and dynamic friction coefficients are 0.2 and 0.18 respectively.

a) Describe all the forces acting on the block and determine the mechanical work done by each of them if the block slides 2 m.

b) What is the net work done on the block?

C) What is the speed of the block after traveling 2 m?
