Answer:


a=0.25\ m/s^2

Step-by-step explanation:

Initial speed of the mobile = 3.2 m/s

Final speed of the mobile = 5.2 m/s

Time, t = 8 s

We need to find the acceleration of the mobile. It can be given by the change in velocity divided by time. So,


a=(v-u)/(t)\\\\a=((5.2-3.2)\ m/s)/(8\ s)\\\\=0.25\ m/s^2

So, the acceleration of the mobile is
0.25\ m/s^2.
