4. A balloon is rising vertically above a level, straight road at a constant rate of 3 ft/sec. Just when the balloon is 78 ft s(t) is increasing by (Simplify your answer.) ft/ sec. above the ground, a bicycle moving at a constant rate of 12 ft/ sec passes under it. How fast is the distance s(t) between the bicycle and balloon increasing 6 seconds later? y(t) s(t) on back x(t) ID: 3.10.33 5. A light shines from the top of a pole 40 ft high. A ball is dropped from the same height from a point 30 ft away from the light. How fast is the shadow of the ball Ball at time t=0 moving along the ground 1 sec later? (Assume the ball falls a distance s = 16t in t sec.) t3D t- 1 sec later 40-ft pole 30 The shadow is moving at a velocity of ft/sec. (Type an integer or a decimal.) ID: 3.10.39
