Physics - Rotational Motion
posted by Robert .
(#1.) A top starting from 40 rad/s takes 200 rad to stop. What is its rotational acceleration? (a constant)
(#2.) A stationary 100 Kg circular object (r= 0.20 m) is on a 35 degree incline. The coefficient of rolling friction between the block and the incline is 0.01. If it moves for 5 seconds, what is the angular displacement of the object at this time? (disregard torque)
