    integrate a(t) from 0 to t the constant of integration will be v(0) integrate again from 0 to t the constant of integration will be s(0)

    It seems take you forever to understand the purpose of initial values :/ V(t) = ∫ a(t) dt = 2sin 5t + C V(0) = 2 sin 0 + C = - 6 -> C = -6 =>S(t) = ∫ v(t)dt = ∫ (2sin5t -6 ) dt = .... + C S(0) = 12 -> C = ...
