Overview
. A motor spins an insulated container he is in (total mass) around on a m long arm at rpm. The coefficient of kinetic friction between the container and the ground is . a) What is the force due to friction of this system? What direction does it point? b) After the motor stops, what is the angular acceleration of the container as it comes to rest? c) After the motor stops, how long does the container take to come to rest?
