Question

The figure shows particles 1 and 2, each of mass m, attached to the ends of a rigid massless rod of length L₁ + L₂, with L₁ = 1.0 m and L₂ = 7.0 m. The rod is held horizontally on the fulcrum and then released. What are the magnitudes of the initial accelerations of (a) particle 1 and (b) particle 2?

Chapter 10, Problem 056 Your answer is partially correct. Try again. The figure shows particles 1 and 2, each of mass m, attached to the ends of a rigid massless rod of length L1 + L2, with L1 = 1.0 m and L2 = 7.0 m. The rod is held horizontally on the fulcrum and then released. What are the magnitudes of the initial accelerations of (a) particle 1 and (b) particle 2?
