10 m/s

Explanation:

Since acceleration is rate of change of speed per unit time and we know the initial velocity is zero then (v-u) / t = a hence v=at where v is the final velocity, u is initial velocity which is zero, t is time and a is acceleration. Substituting the value of acceleration with 2m/s2 and t for 5 s then

V = 5*2=10 m/s
