A rod of mass m and length L, pivoted at one of its ends, is hanging vertically. A bullet of the same mass moving at speed v strikes the rod horizontally at a distance x from its pivoted end and gets embedded in it. The combined system now rotates with angular speed o about the pivot. The maximum angular speed M is achieved for x = XM. Then (A) = (C) XM 3vx L²+3x² = L √3 (B) = (D) M 12vx L² + 12x² = -√3 2L V X L A rod of mass m and length L, pivoted at one of its ends, is hanging vertically.
