5. A question on test asked the students to explain how a barometer can be used to determine the height of a tall building. One student answered that he would measure the length of the barometer, place it on the ground in a convenient location and determine the view angle from the ground to the top of the building. Then he will use the relations between similar triangles to calculate the height of the building. The instructor was puzzled by this answer and asked to student to come to his office. He asked the student again to solve this problem. The student said: "I would go to the top of the building, drop the barometer and measure the time it takes it to hit the ground. Then I'd use the equation for a free-falling body to determine the distanced travelled by the barometer." The instructor insisted on another answer, so the student said: "I'll go to the superintendent of the building and say to him if you tell me the height of the building, I'd give you this barometer." What is the answer the instructor wanted to hear?
