Continued) Consider the situation in the figure where a square block (my) sits stop a triangular wedge (m2). A fope is fixed to a wall and attached to the block such that the rope is rallel to the surface of the wedge. The wedge's top surface makes an angle of theta with respect to the h tion with the same static coefficient us. The system is in equilibrium but if the coefficient of friction between horizontal . As tal. Assume that all surfaces have fric- the block and wedge was any smaller, they would slide relative to each other. The block (my = m) has a mass half as large as the wedge. (c) Draw a free body diagram for my. M1 FBD (M,) M2 d) Identify all Newton's 3rd law force pairs between the box and the trian- gle wedge. Force Pairs Fin = - FW Ffis = - Ptis 12mg (e) Use a coordinate system with positive x up the incline and positive y perpendicular to the wedge's incline. Write out Newton's 2nd law in both the x and y directions for triangle m2. Your answer should be in terms of m, 0, Us, FN(12), FN (ground,2) and g. Identify any quantities that are zero. There is no need to solve for any- thing (i.e. don't solve for a variable in one direction and plug it into the other direction).
