Question 16 (1 point) Problem 1 A spool is made from two disks of mass m = 98 g each connected by a lightweight axle as shown in the diagram. The axle has a radius of r1 -0.80 cm disks have radil of r2 - 4.70 cm. If you hold the thread tight at one end, the thread will begin to unravel as the spool travels downwards. 3: 5 Side view

Answer 1

801: Given mass m=989 = 98x16kg radius of axle 8, = 0.80cm -0.8x10?m m. Torque =Fx8 = ngxri 98x163x9.818 018 X10 70691x103 N-m 2 But Torque T ID cohere I = moment of inertia of Spool. = 1/2 MR² Ta = √ MPAK = 2 M R xalR a 22R where a=ape 2T MR 2x 7.691x102 98x10²x0.8x102 - 19.62 m/s2 acceleration a = 19.62 m/s2
