#2. [Two Crates] Two crates, A and B, of masses mA and mB ( < mA) are pushed on a frictionless horizontal surface by an applied force F, as shown. (a) Draw a carefully labeled free-body diagram for each crate. (b) Write Newton 's 2nd Law equations in horizontal and vertical components for each crate. A B (c) What are the magnitude and direction of the acceleration of the crates (in terms of F, mA, and mB)? (d) What is the magnitude of the normal contact force on crate B due to crate A (in terms of F, mA, and mB)? (e) What is the magnitude of the normal contact force on crate A due to crate B (in terms of F, mA, and mB)? (f) Suppose mA = 20.0 kg,F = 50.0 N, and the acceleration of the crates is a = 2.00 m/s2. What is the mass of crate B (in kg)? Suppose the crates are switched in positions, but they are pushed by the same applied force F as before, as shown. (g) How would the acceleration of the crates now compare
