b) What are the magnitude and direction of F32, the force on crate 3 from crate 2? c) What are the magnitude and direction of F23, the force on crate 2 from crate 3? d) If the crates then slide onto a polished floor, where the coefficient of kinetic friction is less than 0.700, is the magnitude of F32 more than, less than or the same as it was when the coefficient was 0.700? Explain how you know.
