WebCOM of a uniform rod is the middle point of the rod. From the figure, the COM of rod along x-axis is ( l 1 2, 0 ). On the other hand, COM of rod along y-axis is ( 0, l 2 2 ). These rods, therefore, can be considered as particles at these positions. Thus, the L-shaped rod system reduces to the case of two particles system separated by a distance. WebThe center of mass is a point in a system that responds to external forces as if the total mass of the system were concentrated at this point. The center of mass can be …

WebThe momentum carried by the particle is mv; the moment of inertia of the rod about its center (where its center of mass is, around which it will rotate) is Ml^2/12. The linear impulse on the end of the rod is mv, so the angular impulse is 2mv/l. Therefore the angular velocity is angular momentum/moment of inertia, so 24mv/Ml^3.
