------- Additional Questions  --------

A spool has a thin, negligible-mass cable attached to it which is pulled with an acceleration of 1.5 m/s^2.  The diameter of the spool is 6.0 cm and it rotates on a frictionless bearing from rest. After 1.0 m of the cable has been unwound, what is the angular speed of the spool in revolutions per minute? Assume the cable is pulled at an angle that allows for the maximum speed to be obtained.
