(1) Find a point P in the first quadrant on the curve f(x) = 2 such that the rectangle with
sides on the coordinate axes and a vertex at P has the smallest possible perimeter.
(2) Let s(t) = 5t2 – 22t be the position function of a particle moving alon a coordinate line,
where s is in feet and t in seconds.
(a) Find the maximum speed of the particle during the interval 1 < t < 3.
(b) When during the time interval 1 <t < 3, is the particle farthest from the origin? What
is its position at that instant?
