Answer:
4) a) [tex]s = +4\,mi[/tex], b) [tex]\Delta s = 2\,mi[/tex], 5) a) [tex]s = -2\,mi[/tex], b) [tex]\Delta s = 10\,mi[/tex]
Explanation:
4) Let assume that distance with respect to origin is positive at east, while distance is negative at west.
a) The initial displacement is:
[tex]s = +4\,mi[/tex]
b) The distance travelled is:
[tex]\Delta s = 2\,mi[/tex]
[tex]\Delta s = 2\,mi[/tex]
5) a) The final displacement is:
[tex]s = -2\,mi[/tex]
b) The total distance travelled is:
[tex]\Delta s = 2\,mi + 6\,mi + 2\,mi[/tex]
[tex]\Delta s = 10\,mi[/tex]
