Problem: An object of mass 1.1kg is placed 0.2m from the axis of a rotating turntable of variable speed. The coefficient of static friction between the object and the table is 0.13.
Part I: When the speed of the turntable is slowly increased, find the number of revolutions per minute at which the object just starts to slide off.
I need help to find the number of revolutions per minute at which the object just starts to slide off.
