Ronch [10]

When a number has the |absolute value|, it refers to the amount of units the number is from 0. (you can think of a timeline)
|3| is 3 units away from zero
|-5| is 5. it is NOT -5 units from 0, since a number cannot be -5 units away.
Basically, these lines | x | will make the number positive.

answer
-5,-2, | -2 |, | 3 |, 8

a sprinter increases the speed from 0 meters per second to 9 meters per second in 2 seconds. what is the acceleration

mote1985 [20]

Answer:

The acceleration is

$4.5 {ms}^{ - 2}$

Step-by-step explanation:

Use the equation of motion,

$v = u + at$

where u=0m/s is the initial speed, v=9m/s is the final speed and t=2 seconds is the time.

We substitute the values into the equation and solve for the acceleration, a

$9 = 0 + a(2)$

This means that;

$9 = 2a$

Divide both sides by 2 to get:

$a = \frac{9}{2}$

$a = 4.5 {ms}^{ - 2}$
