Consider each piece of evidence listed below and sort it into the correct bin based on whether it supports a sudden cause for the demise of the dinosaurs or whether it could also be consistent with a gradual cause leading to their demise over many thousands or more years.

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 .
