Answer:
![0.28 m/s^2](https://tex.z-dn.net/?f=0.28%20m%2Fs%5E2)
Explanation:
Acceleration is given by
![a=\frac{v-u}{t}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7Bv-u%7D%7Bt%7D)
where
u is the initial velocity
v is the final velocity
t is the time interval
In this problem:
is the initial velocity
is the final velocity
t = 2 s is the time
Substituting, we find the acceleration:
![a=\frac{2.78-2.22}{2}=0.28 m/s^2](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B2.78-2.22%7D%7B2%7D%3D0.28%20m%2Fs%5E2)
