In a ballistic pendulum an object of mass m is fired with an initial speed v0 at a pendulum bob.
Find an expression for v0, the initial speed of the fired object.
An experiment is done to compare the initial speed of bullets fired from different handguns: find the ratio of the initial speed of the 9 mm bullet to the speed of the .44-caliber bullet, v0,9/v0,44
During an earthquake, the floor of an apartment building is measured to oscillate in approximately simple harmonic motion with a period of 1.90 seconds and an amplitude of 8.35 cm.
Determine the maximum speed of the floor during this motion.
Determine the maximum acceleration of the floor during this motion.
A mass-spring system is in SHM in the horizontal direction. If the mass is 0.25 kg, the spring constant is 15 N/m, and the amplitude is 15 cm, what is the maximum speed of the mass? Where does this occur? What is the speed at a half-amplitude position?Click for More...
Standing waves on a guitar string form when waves traveling down the string reflect off a point where the string is tied down or pressed against the fingerboard. the entire series of distortions may be superimposed on a single figure, like this (intro 2 figure) , indicating different moments in time using traces of different colors or line styles.
What is the wavelength of the longest wavelength standing wave pattern that can fit on this guitar string? How does the overtone number relate to the standing wave pattern number, previously denoted with the variable n?

Traveling waves propagate with a fixed speed usually denoted as v (but sometimes c). The waves are called __________ if their waveform repeats every time interval T. The fundamental relationship among frequency, wavelength, and velocity is. If the velocity of the wave remains constant, then as the frequency of the wave is increased, the wavelength __________.
