When released from rest, block 2 falls2.00 m in 6.00 s (without the cord slipping on the pulley).a) What is the angular acceleration of the pulley?Applying one of the kinematic equations to block 2,we get the acceleration of the block.d = (1/2)at2 ⇒ a = 2d/t2 = 0.111 m/s2Since the cord does not slip on the pulley, thetangential acceleration of the pulley is equal to theacceleration of the blocks. The angular accelerationof the pulley isαR = at = a ⇒ α = a/R = 0.370 rad/s2b) What is the pulley's rotational inertia?Newton’s 2nd law applied to the blocks yield tensions T1 and T2.m1a = T1 – m1g ⇒ T1 = m1(a + g) = 54.55 Nm2a = m2g – T2 ⇒ T2 = m2(g – a) = 77.51 NApplying Newton’s 2nd law to the pulley, the rotational inertia of the pulley isIα = T2R – T1R ⇒ I = (T2- T1)R/α = 18.6 kg·m
