Question

While traveling along a highway a driver slows from 24 m/s to 15 m/s in 12 seconds. What is the automobile’s acceleration?

Answer 1

-0.75
Because (final velocity -initial velocity)/time

Answer 2

-0.75
`m/s^(2)`

Step-by-step explanation:

a =
`(v2-v1)/(t)` =
`(15 m/s - 24m/s)/(12s)` = -0.75
`m/s^(2)`

Hope this helps!!
