Assertion: An object has a negative acceleration.
Reason: The velocity of an object decreases in the same direction.

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.
