The initial acceleration of end B in a suspended rod system, where a rod of length 61.0 cm and mass 2.10 kg is supported by two strings, is determined after cutting the string on side B. Applying Newton's 2nd law for rotation, the acceleration can be calculated using the formula a = τ/I, where τ is the torque and I is the moment of inertia. The moment of inertia for the rod about its end is I = (1/3)ml², leading to a definitive calculation of the initial acceleration of end B once the string is severed.
