A weather balloon is rising vertically at the rate of 5 meters per second. An observer is standing on the ground 300 meters from where the balloon was re- leased. (a) How fast is the distance between the the observer and the balloon changing when the balloon is 300 meters high? (b) How fast is the angle of elevation from the observer's perspective changing at the instant the balloon is 300 meters high?
