Two masses m1= 3.2 kg and m2= 8.9 kg are attached to each other by a string passing through a massless pulley of radius R= 131 cm. M1 is also attached to vertical spring of stiffness constant k= 12 N/m and equilibrium length 5h, while m2 is held at a height of h= 2.1 m initially. (Take the g= 9.8 m/s^2) If the system is released from rest. 5h www.3 R |m| h b) Repeat the question for the case where the pulley has a mass, hence a moment of inertia /= 14 kg.m^2.
