Position can best be described as
a. the speed of an object.
b. the location of an object.
c. the acceleration of an object.
d. the time it takes an object to travel from one place to another.

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 .
