A dog traveling 4.75 m/s, south is at a point 76.4 m, north of a fire hydrant. At a point 16.9 m, south of
the same hydrant, the dog's velocity is 8.31 m/s, south.
Assuming constant acceleration, how long did this take?
Calculate the displacement of a car that is constantly
accelerating at 165 m/s2, east if it has an initial velocity of 90.0
km/h, west and it accelerates for 0.0410 seconds.

Introduction
Many objects move back and forth; that is, they move along a line first in one direction, and then move back the other
way. A ball tossed vertically into the air is an example of something wh
