Two blocks of identical masses m₁ = m₂ = 1.0 kg are connected by a light string that passes through a cylindrical pulley of mass M = 200 g and radius R = 10 cm. Block m₁ is hung.

a) What is the tension in the string?
b) What is the acceleration of the system?
c) What is the angular acceleration of the pulley?
d) What is the coefficient of kinetic friction between the blocks and the table?
