Question

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

Answer 1

Answer:

2 m/s

Step-by-step explanation:

Do 16 / 8 = 2

Check by doing 8 * 2 = 16

Answer 2

Answer:

-2 m/s

Step-by-step explanation:

vf= velocity final

vi= velocity initial

t= time

a= acceleration

a=vf-vi divied by time\\

a= 0-16 over 8\\

a=-2 m/s
