Question 1111609: On a sunny, warm day, a student decides to fly a kite on the col- lege green just to relax. His kite takes off and soars. He lets all 150 feet of the string out and attracts a crowd of onlookers. There is a slight breeze, and a spectator 90 feet away from the student notices that the kite is directly above her. Unlike a real kite, this math-question kite has the string going in a straight line from the student to the kite. How high is the kite from the ground?

Question 1111614: Train tracks are made of metal. Consequently, they expand when it�s warm and shrink when it�s cold. When riding in a train, you hear the clickety-clack of the wheels going over small gaps left in the tracks to allow for this expansion. Suppose you were a beginner at laying railroad tracks and forgot to put in the gaps. Instead, you made a track 1 mile long that was firmly fixed at each end. On a hot day, suppose the track expanded by 2 feet and therefore buckled up in the middle, creating a triangle.
Roughly how high would the midpoint be?
