Work done by friction on a conveyor belt
28/03/2016 · At a factory, a 300kg crate is dropped vertically from a packing machine onto a conveyor belt (I apologize for not having a picture) moving at a speed of m/s. The coefficient of kinetic friction between the belt and the crate is .40. After a short time, slipping between the belt and the crate ceases and the crate then moves along the belt.
