A body moving with a constant acceleration travels the distances 3 m and 8 m respectively in 1 s and 2 s. Calculate : (i) the initial velocity, and (ii) the acceleration of body.

Explanation

To solve the problem step by step, we will use the equations of motion under constant acceleration.

### Given:
1. Distance traveled in the first second (s1) = 3 m
2. Distance traveled in the second second (s2) = 8 m
3. Time for the first distance (t1) = 1 s
4. Time for the second distance (t2) = 2 s
