Arunner increases her speed from 3.1 m/s to 3.5 m/s during the last 15 seconds of her run, what was her acceleration during her big push to the finish ?

Acceleration = velocity/time
A= 3.5m/s/15s
A= 0.23m/s^2

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.

The geological theory that states that pieces of earth's lithosphere are in constant slow motion is the theory of plate tectonics.
