A particle moves along a line with velocity function v(t) = t^2 - 2t, where v is measured in meter per second.
a. Find the displacement traveled by the particle during the time interval [0, 5].
b. Find the distance traveled by the particle during the time interval [0, 5].
[Hint: Recall that the displacement of a particle moving along a line given by the position function s(t) over a time interval [a, b] is given by s(b) - s(a) = ∫[a,b] v(t) dt and the total distance travelled is given by ∫[a,b] |v(t)| dt.]
