2. A particle initially at the origin moves along the xaxis with velocity v (t) = (2 − t) t.
(a) (3 points) Find the particle’s position at time t = 4. (b) (3 points) What is the total distance traveled by the particle during the time
interval from t = 0 to t = 4? (Be careful!) 3. (6 points) Find the area of the region bounded by the curves y = cos(x), y = cos(2x),
the y axis and the line x = π .

each of the following solids, write down (but do not evaluate) a deﬁnite integral that
computes its volume:
(a) The solid obtained by rotating R about the xaxis (b) The solid obtained by rotating R about the y axis (c) The solid whose base is R and whose crosssections parallel to the y axis are
squares. ...
