86. A solid cylindrical pulley
with a mass of 1.00 kg and a radius
of 0.25 m is free to rotate about its
axis. An object of mass 0.250 kg is
attached to the pulley with a light
string (Figure 8-55). Assuming the
string does not stretch or slip, calcu-
late the tension in the string and the
angular acceleration of the pulley. Figure 8-55 Problem 86
