An object is moving with an initial velocity of 5.5 m/s. It is then subject to a constant acceleration of 2.5 mis2 for 15 s. How far will it have traveled during the time of its acceleration? Three significant are
needed here."14.5 m/s"

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 .
