## anonymous one year ago The velocity function, in feet per second, is given for a particle moving along a straight line. v(t) = 2 cos(t), 0 ≤ t ≤ 3π Find the total distance that the particle travels over the given interval.

$\int\limits_{0}^{3\pi} v(t) dt$

there's a "2" missing there but you get the idea, the straight integral will give displacement, you want distance.....
