5.34. Set Up: Constant velocity means for each crate. Apply to each crate, with to the right. Solve: The free-body diagrams for each crate are shown in Figure 5.34. Figure 5.34 (a) for each crate gives and and for A gives for B gives Adding these two equations gives (b) 5.35. Set Up: Use the information about the motion to find the acceleration of the puck and then use to relate a to the friction force. Take to be in the direction the puck is moving. Solve: and gives The free-body diagram for the puck is given in Figure 5.35. gives and gives Figure 5.35 m k 52 ma x mg 52 a x g 52 2 1.53 m / s 2 9.80 m / s 2 5 0.16. y x mg n f k 5 m k n v 2m
