When the tucurui dam was constructed in northern brazil, the lake that was created covered a large forest of valuable hardwood trees. it was found that even after 15 years underwater the trees were perfectly preserved and underwater logging was started. during the logging process a tree is selected, trimmed, and anchored with ropes to prevent it from shooting to the surface like a missile when cut. assume that a typical large tree can be approximated as a truncated cone with a base diameter of 13 ft, a top diameter of 7.6 ft, and a height of 82 ft. determine the resultant vertical force that the ropes must resist when the completely submerged tree is cut. the specific gravity of the wood is approximately 0.6 .

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
