Q3. A 70-kg man is standing on the end of a 250-kg log that is floating in the water. Both the and the log are at rest, and the log is 3.0 m long. If the man walks to the other end of the log, how far will the log move in the water? Ignore any forces exerted on the log by the water. (x = 0.66 m or 66 cm to the right)

Q1 A spherical buoy has a diameter of 1.5 m. weighs 8.50 kN. and is anchored to the sea floor with a cable as is shown in Fig. E2.10a. Although the buoy normally floats on the surface, at certain times the water depth increases so that the buoy is completely immersed as illus- Irated. For this condition what is the tension of the cable? Seawater Buoy Cabie I FIGURE E2.10

Balancing carefully, three boys inch out onto a horizontal tree branch above a pond, each planning to dive in separately. The third boy in line notices that the branch is barely strong enough to support them. He decides to jump straight up and land back on the branch to break it, spilling all three into the pond. When he starts to carry out his plan, at what precise moment does the branch break? Explain. Suggestion: Pretend to be the third boy and imitate what he does in slow motion. If you are still unsure, stand on a bathroom scale and repeat the suggestion.
