數學系卡安很閒 所以決定拯救沒辦法用slader和chegg的莘莘學子
33. A balloon and a bicycle A balloon is rising vertically above a
level, straight road at a constant rate of 1 ft/sec. Just when the
balloon is 65 ft above the ground, a bicycle moving at a constant
rate of 17 ft/sec passes under it. How fast is the distance s(t)
between the bicycle and balloon increasing 3 sec later?
