Name AP Physics Vibrations and Waves Review 1. A mass M at the end of a spring oscillated with a frequency of 0.88 Hz. When an additional H.600 kg mass is added, the frequency changes to {160 Hz. What is the value of M? 2. A mass attached to the end of a spring is stretched a distance & from equilibrium and then released. At what distance from equilibrium will it have: A} Avelocity equal to half its maximum velocity B} An acceleration equal to half its maximum acceleration 3. A 25.0 g bullet strikes a 0.600 kg block attached to a horizontal spring with a k=6?0 me and sets it into vibration with an amplitude of {1215 rn. What is the speed of the bullet before the collision? iassu me inelastic collision] 4. A pendulum makes 36 vibrations in 50 seconds. Calculate its period and its frequency
