Answer:
v = - 0.88 m/s
Explanation:
Average velocity is defined as the ratio of displacement and time
so here as we can see that the displacement is the change in the position of the object
initially object is placed at x = 8 m
final position of the object is x = 1
so the displacement is given as
[tex]d = x_f - x_i[/tex]
[tex]d = 1 - 8 = -7 m[/tex]
now the time taken by the object
[tex]\Delta t = 22 - 14 = 8 s[/tex]
now by the formula of average velocity we know
[tex]v = \frac{displacement}{time}[/tex]
[tex]v = \frac{-7}{8} = - 0.88 m/s[/tex]
