A weather balloon is rising vertically at 40 meters per second. An observer is standing on the ground 24 meters from the point at which the balloon was released. Determine (in meters per second) the rate at which the distance between the observer and the balloon is changing when the balloon is 32 meters high (and hence 40 meters from the observer). 1. rate = 34 meters/sec 2. rate = 33 meters/sec 3. rate= 36 meters/sec 35 meters/sec 5. rate= 32 meters/sec 4. rate =
