33. 34. You are observing a rocket launch from a point 4000 feet from the launch pad (Fig. 26). When the observation angle is m3 . the angle is increasing at 1':le feet per second. How fast is the rocket traveling? h (Hint: 6 and h are functions of t. tan(6)=m so d d h dh a tan([-)) = 5(m) . Then solve for a .) You are observing a rocket launch from a point 3000 feet from the launch pad. You heard on the radio the when the rocket is 5000 feet high its velocity is [00 feet per second. (a) What is the angle of elevation ofthe rocket when it is 5000 feet up? (b) How fast is the angle of elevation increasing when the rocket is 5000 feet up?
