(b) The coefficient of kinetic friction between a 40 kg crate and the ware-
house floor is 70% of the corresponding coefficient of static friction.
The crate falls off a forklift that is moving at 3 m/s and then slides
along the warehouse floor for a distance of 2.5 m before coming to
rest. What is the coefficient of static friction between the crate and
the floor?
Can i get help with this problem?
