Answer:
The acceleration is: 
Explanation:
Recall that acceleration is defined as the change of velocity over the time it took to produce this change. This is expressed mathematically as:
with 
being the initial velocity of the person (in our case 4 m/s);
being his final velocity (in our case 15 m/s);
and the difference 
the time the change in velocity took (in our case 1 second).
Therefore in our example, the person's acceleration is:
