Supposing that the pulley has a finite moment of inertia I, find the acceleration of mass m. m g I/R2 + m + m0 (B) g m (C) 0 g mm (D) g m + m0 0 m−m (E) g I/R2 (A) m0 I g m 2. Two equal masses m1 = m2 = m are connected by a spring having Hooke’s constant k. If the equilibrium separartion is `0 and the spring rests on a frictionless horizontal surface, then derive ω0 the angular frequency. (A) p k/m p (B) 2k/m p (C) 3k/m p (D) 2 k/m p (E) g/`0 k m1 m2
