The figure below shows particles 1 and 2, each of mass m, attached to the ends of a rigid massless rod of length L1 + L2, with L1 = 20 cm and L2 = 84 cm. The rod is held horizontally on the fulcrum and then released.Here is the URL to the figure: http://www.webassign.net/hrw/hrw7_10-43.gif(a) What is the magnitude of the initial acceleration of particle 1?(b) What is the magnitude of the initial acceleration of particle 2?
