Two crates of mass m₁= 35 kg and m₂= 15 kg are stacked on the back of a truck (Fig. P4.54). The frictional forces are strong enough that the crates do not slide off the truck. Assume the truck is accelerating with α = 1.7 m/s². Draw free-body diagrams for both crates and find the values of all forces in your diagrams.
