Figure 6-32 shows three crates being pushed over a concrete floor by a horizontal force
Chapter 6, Problem 26(choose chapter or problem)
Figure 6-32 shows three crates being pushed over a concrete floor by a horizontal force of magnitude 440 N. The masses of the crates are m1 30.0 kg, m2 10.0 kg, and m3 20.0 kg. 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 floor, 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? m1m2 m3FFigure 6-32 26.
