The fundamental frequency of a pipe that is open at both ends is 598Hz .
1. How long is this pipe? Use v = 344 m/s.
2. If one end is now closed, find the wavelength of the new fundamental.
3. If one end is now closed, find the frequency of the new fundamental.
A barefoot field-goal kicker imparts a speed of 26 m/s to a football at first at rest. If the football has a mass of 0.24 kg and the If the football has the mass of 0.24 kg and the time of contact with the ball is 0.037 s, what is the force exerte..
A major league pitcher can throw a baseball in excess of 42.9 m/s. If a ball is thrown horizontally at this speed, how much will it drop by time it reaches the catcher who is 18 m away from the point of release.
