We have,
u = 0 , a = 2 , t = 10 , v = ?
Since, v = u+at
v = 0 + (2*10)
v = 0 + 20
v = 20 m/s.
Note that this formula is only applicable when acceleration is constant and it is given in the question that the body accelerates for 10 seconds. If you were to find the velocity after 10 seconds, then by simply we can say that after 10 seconds the body starts moving with uniform velocity as no acceleration is applied on it.
