Question

A Car accelerates from 4 m/s to 16 m/s in 4 seconds. What is the car's

acceleration?
O 12 m/s^2
3 m/s^2
4 m/s^2
O 1 m/s^2

Answer 1

4 m/s^2

that is the right acceleretion a car

Answer 2

I believe that the answer is 3 m/s^2

Step-by-step explanation:

since acceleration is final velocity minus initial velocity divided by time, we can plug in known values and solve.

a=(f-i)/t

a=(16-4)/4

a=12/4

a=3

3m/s^2 is the acceleration
