Need help on solving Part A) and Part B)

A particle is released as part of an experiment. Its speed t seconds after release is given by v(t) = - 0.41- + 4t, where v(t) is in meters per second. a) How far does the particle travel during the first 2 sec? b) How far does it travel during the second 2 sec? a) The particle travels meters in the first 2 sec. (Round to two decimal places as needed.) b) The particle travels meters in the second 2 sec. (Round to two decimal places as needed.)
