The acceleration of an object is given by a(t) = cos(nπ), and its velocity  at time t = 0 is   (1/(2π)). Find both the net and the total distance traveled in the  first  1.5 seconds.

$$\mathrm{The}\:\mathrm{acceleration}\:\mathrm{of}\:\mathrm{an}\:\mathrm{object}\:\mathrm{is}\:\mathrm{given}\:\mathrm{by}\:\mathrm{a}\left(\mathrm{t}\right)\:=\:\mathrm{cos}\left(\mathrm{n}\pi\right),\:\mathrm{and}\:\mathrm{its}\:\mathrm{velocity} \\ $$$$\mathrm{at}\:\mathrm{time}\:\mathrm{t}\:=\:\mathrm{0}\:\mathrm{is}\:\:\:\frac{\mathrm{1}}{\mathrm{2}\pi}.\:\mathrm{Find}\:\mathrm{both}\:\mathrm{the}\:\mathrm{net}\:\mathrm{and}\:\mathrm{the}\:\mathrm{total}\:\mathrm{distance}\:\mathrm{traveled}\:\mathrm{in}\:\mathrm{the} \\ $$$$\mathrm{first}\:\:\mathrm{1}.\mathrm{5}\:\mathrm{seconds}. \\ $$
