Chapter 4, Problem 54P
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 a = 1.7 m/s2. Draw free-body diagrams for both crates and find the values of all forces in your diagrams.

A horizontal applied force F = 35 N is used topush two blocks along a frictionless frozen lake. Block 1 hasmass m1 = 1.2 kg and block 2 has mass m2 = 2.4 kg. Thereis a static friction force with coefficient µs between the twoblocks that prevents block 1 from slipping downwards. Draw three free-body diagrams: block 1, block 2, and the two-block system. Label the forces. What is the magnitude of the acceleration of the two blocks?What is the minimum value of µs needed to stop block 1 from slipping? If you didn’t answer theprevious part, let a = 16 m/s2.
Please answer A and B. If possible, Question F too. Thanks!
