RECTILINEAR MOTION IN STRAIGHT LINE how do we know the time with the initial velocity of 1m/s  in this problem?  Should i assume that the time in that moment was 0? or i should include the time 2sec in answering all the expressions? Please I need an answer from an expert so i should be sure about my analyzation thankyouuu!

4. A certain particle is travelling in a straight line governed by the equation a = vš m / s². If the particle is found
to have an initial velocity of 1m / s, determine an equation relating velocity and time, velocity and displacement
and the acceleration of the particle at t = 2s.
