There are three crates being pushed over a concrete floor by a horizontal force, There are three crates being pushed over a concret, of magnitude 440 N. The masses of the crates are m1=30.0 kg, m2=10.0kg, m3=20.0kg. The coefficient of kinetic friction between the floor and each of the crates is 0.700.
a. What is the magnitude F32 of the force on crate 3 from crate 2?
b. If the crates then slide onto a polished flow, where the coefficient of kinetic friction is less than 0.700, is magnitude F32 more than, less than or the same as it was when the coefficient was 0.700?
