Q1. A ball is thrown horizontally from the roof of a building 56 m tall and lands 33 m from the base. What was the ball's initial speed?

Q2. The physics of wind instruments is based on the concept of standing waves. While the player blows into the mouthpiece, column of air inside the instrument vibrates, and standing waves are produced. Though the acoustics of wind instruments is complicated, a simple description in terms of open and closed tubes can help in understanding the physical phenomena related to these instruments. For instance, the flute can be described as an open-open pipe because a flutist covers the mouthpiece of flute only partially. Meanwhile, a clarinet can be described as an open-closed pipe as the mouthpiece of the clarinet is almost completely closed by the reed.
