A tuning fork is struck, producing a pure
tone as its tines vibrate. The vibrations are modeled by the
function
v(t) = 0.7 sin(880t)
where u(t) is the displacement of the tines in millimeters at
time t seconds.
Find the frequency of the vibration, that is, the number
of times the fork vibrates per second.
The equation of motion of a particle in
simple harmonic motion is given by:
x(t) = 0.3cos(wt), where x is in meters
and t is in seconds. At x = 0, the
particle's velocity is v = -1.256 m/s. The
period of oscillation, T, equals:
O 1.5 sec
O 0.25 sec
O 0.5 sec
O 1 sec
O 3 sec
The equation of motion of a particle
in simple harmonic motion is given
by: x(t) = 0.1cos(wt), where x is in
meters and t is in seconds. At x = 0,
the particle's velocity is v = -1.256
m/s. The period of oscillation, T,
