A balloon is rising vertically above a level, straight road at a constant rate of 5 it/sec. s(t) is increasing by it/sec. Just when the balloon is 29 ft above the ground, a bicycle moving at a constant rate of (Simplify your answer.) 11 ft/sec passes under it. How fast is the distance s(1) between the bicycle and balloon increasing 3 seconds later? y(t) s(t)A spherical balloon is inflating with helium at a rate of 300x ft /min. How fast is the balloon's radius increasing at the instant the radius is 5 ft? How fast is the surface area increasing
