I need help with parts a-f, thank you!

[13%) Problem 2: A block with a mass of m = 15 kg rests on a wooden plank. The coefcient of static friction between the block and the plank is #5 = 0.62. One end of the board is attached to a hinge so that the other end can be lifted forming an angle, 9, with respect to the ground. Assume the xaxis is along the plank : y as shown in the gure. \\/ x mhccxpcrttaxom' a A 17% Part (2) Please use the interactive area below to draw the Free Body Diagram for this block assuming it is in static equilibrium.
