Tony charges a capacitor and then discharges it through a resistor. He notices that, after two time constants, the voltage across the capacitor has decreased to of its value just prior to the initiation of the discharge.

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.
