Attached to each end of a thin steel rod of length 1.20 m and mass6.40 kg is a small ball of mass 1.06 kg. The rod is constrained torotate in a horizontal plane about a vertical axis through itsmidpoint. At a certain instant, it is rotating at 39.0 rev/s.Because of friction, it slows to a stop in 32.0 s. Assuming aconstant retarding torque due to friction, compute

(a) the angular acceleration,

(b) the retarding torque,

(c) the total energytransferred from mechanical energy to thermal energy by friction,and

(d) the number of revolutions rotated duringthe 32.0 s.
