Problem #7 (15 points) - Computing Acceleration And Speed The figure below shows two uniform rods, each of mass m and length L = 7 m, so that they are right angles to each other. (a) The initial position of the two rods when released from rest and gravity acts down (b) The new position (in bold) of the two rods and gravity acts down a.) (7 points) The two-rod system is set to rotate about an axis (O) coming out of the page and passing through the left end of the horizontal rod. If the two-rod system is released from rest as in figure (a), determine the angular acceleration of the two-rod system at the moment it is released. b.) (8 points) Determine the angular speed of the two-rod system when it reaches the position shown in bold in figure (b).
