Question

What is the average velocity of the object between 14 and 22 seconds

Answer 1

Use the slope equation. It’s 1-8 Meters which is 7. And it’s 22-14 seconds. So the answer is d

Answer 2

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

$d = x_f - x_i$

$d = 1 - 8 = -7 m$

now the time taken by the object

$\Delta t = 22 - 14 = 8 s$

now by the formula of average velocity we know

$v = \frac{displacement}{time}$

$v = \frac{-7}{8} = - 0.88 m/s$
