g. Water is being poured at the rate of 5 m/sec into an inverted conical tank of radius 10 m and altitude 20 m. How fast is the water level rising when the water level is at 8 m? (Note: Here you will be using the concepts of similar triangles in order to rewrite the radius in terms of the height.)

Transcribed Image Text:e An airplane flying on a straight flight path will be exactly above a radar tracking
station, which is 5,000 km below the path. When the distance of the plane from the
station is 40,000 km, this distance decreases at the rate of 8,000 km/hr. At what rate is
the plane flying at that instance?

f. A truck travelling southwards at 40 kph and a car traveling eastward at a rate of 60 kph
are headed for an intersection. At what rate are the vehicles approaching each other
when the truck is 1 km from the intersection while the car is 2 km from the
intersection?
g. Water is being poured at the rate of 5 m³/sec into an inverted conical tank of radius
10 m and altitude 20 m. How fast is the water level rising when the water level is at
8 m? (Note: Here you will be using the concepts of similar triangles in order to rewrite
the radius in terms of the height.)
