NOTE: You must draw a proper FBD for every problem and clearly indicate all forces and couples that are present for the problem. State all quantities that are known (i.e., ones that are prescribed or implied by the problem). Problem 1: The total force exerted on the highway sign by its weight and the most severe anticipated winds is $\vec{P} = 3P\hat{i} - 2P\hat{j}$. Determine the reactions at the fixed support O.

2. A pendulum bob of mass 1.5 Kg attached to a massless rod of 2.0m, anchored at o, with an initial horizontal position swings down and strikes a stationery 2kg block in a head on elastic collision. The 2.0Kg block is initially directly below the pivot o. 1.5 Kg 2m 0 A Pivot n=19.6N fr= \mu x N F_N=(0.35)(19.6N) F_r= 6.86N 6.86N V= 0mls 2 Kg W= 2x9.8= 19.6N a. What is the speed of the bob just before it strikes the 2kg block? V= \sqrt{2gh} = \sqrt{2x9.8x2.0} = 6.26 mls b. Find the speed of the bob and the 2kg block just after collision. Elastic Collision M_A v_{A1} + M_B v_{B1} = M_A v_{A2} + M_B v_{B2} (1.5kg)(6.261mls) = (1.5kg)v_{A2} + 2kg v_{B2} c. If the coefficient of kinetic friction between the 2.0Kg block and the floor is 0.35, how far does the block travel after collision.
