4. (ROTATIONAL DYNAMICS) The figure below shows particles 1 and 2, with masses m1 = 0.05 kg and m₂ = 0.1 kg, respectively, attached to the ends of a rigid massless rod of length L1 + L2, with L₁ 20 cm and L2 80 cm. The rod is held horizontally on the fulcrum (or triangular support) and then released. (a) What is the magnitude of the tangential acceleration of particle 1 immediately after the rod is released? (b) What is the magnitude of the tangential acceleration of particle 2 immediately after the rod is released? (c) Where would the fulcrum have to be located in order for the system to instead balance (rather than rotate) when released? Find and report the necessary distance of the fulcrum from particle 1. +4+ L₂ 2
