betw A hot air balloon rising vertically is tracked by an observer located 7 km from the lift-off point. At a certain moment, the inter angle between the observer's line of sight and the horizontal is and it is changing at a rate of 0.5 rad/min. How fast is the balloon rising at this moment? be the height of the balloon (in km), t be time (in minutes), and 0 the angle between the line-of-sight and the horizontal y Let and (in radians).
