Asked by Mary
An electric clock is hanging on the wall in the living room. The clock is unplugged, and the second hand comes to a halt over a brief period of time. During this period, what is the direction of the angular acceleration of the second hand?
a. clockwise
b. counterclockwise
Why?
I choose clockwise but I am not sure why. Please help!
angular acceleration= wf-wi/time
Notice that wf is zero, so if clockwise is positive, then angular acceleration is the negative of that.
