Expert Answer:

When a particle is seen at x=0 and t=0 and the acceleration of the particle depends on time as
a=(2m/s3)t+(1m/s2) i.e a=2t+1 along x-axis.
Also, if that particle is at rest at the origin at time t=0, then at t=6 sec, its velocity is calculated by using the relation that acceleration is the rate of change of velocity with respect to time i.e begin mathsize 14px style straight a equals dv over dt end style
Therefore, at time t=6 secs, the velocity of the particle is 42 m/s.
