A Car traveling at 16 m/s starts to decelerate steadily. It comes to a complete stop in 8 seconds, what is its acceleration?

VI Initial velocity: 16 m/s

VF Final velocity: 0 m/s

t: 8s  

Acceleration/A is unknown

vf = Vi+a*t  

0 = 16 + a * 8

0-16 = 16-16 + a * 8

-16= a 8 or 8a = -16

8a/8 = -16/8

=-2 m/s

The acceleration is -2m/s (decelerates)

The acceleration is -2m/s (decelerates)

Step-by-step explanation:

VI Initial velocity: 16 m/s

VF Final velocity: 0 m/s

t: 8s  

Acceleration/A is unknown

vf = Vi+a*t  

0 = 16 + a * 8

0-16 = 16-16 + a * 8

-16= a 8 or 8a = -16

8a/8 = -16/8

=-2 m/s

The acceleration is -2m/s (decelerates)

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

the correct answers i think are b. and d.

give me brainliest if it is correct!
