Question

Need help find last answer for this cal-4 class.

The graph shows the displacement from equilibrium of a mass-spring system as a function of time after the
vertically hanging system was set in motion at time t = 0. Assume that the units of time are seconds, and
the units of displacement are centimeters. The first t-intercept is (0.25, 0) and the first minimum has
coordinates (0.75, –3).
(a) What is the period T of the periodic motion?
T =
2
seconds
(b) What is the frequency f in Hertz? What is the angular frequency w in radians / second?
f =
1/2
Hertz
W =
2pi/2
radians / second
(c) Determine the amplitude A and the phase angle y (in radians), and express the displacement in the
form y(t) = A cos(wt – y), with y in meters.
y(t)
.03cos(2pi/2(t+2.25))
meters
(d) With what initial displacement y(0) and initial velocity y'(0) was the system set into motion?
y(0)
.03cos(2pi/2(2.2: H
meters
y'(0)
meters / second
