Problem 2: A block with a mass ofm = 1.5 kg rests on a wooden plank. The coefficient of static friction between the block and the plank is #3 = 0.44. 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 x-axis is along the plank as shown in the gure. \\/ X l'thcmpcr'll :1.cn rn Part (2) Please use the interactive area below to draw the Free Body Diagram for this block, assuming it is in static equilibrium. If necessary, use F5 for the force of static friction, and Fk for the force of kinetic friction. FBD . Force Labels: Fn, Fg, Fs, Fk, a, v Angle Labels: 45, 0, 90, 135, 180, 225, 270, 315, 8 Part (b) Assuming the xdireetion is along the plank as shown, find an expression for the magnitude of the force of gravity in the y-direction, F g}, perpendicular to the plank in terms of given quantities and variables available in the palette
