Answer 1

Answer:

                                                                                                                                                 

Explanation:

Answer 2

Initial velocity (u) = distance/time
= 3/1
= 3m/s

Final velocity (v) = distance/time
= 8/1
= 8m/s

Acceleration = (v - u) / t
= (8 - 3) / 2
= 5/2 m/s^2

(Here I assumed you meant the body covers 8m in 2nd second not in 2s)
