- Homework Statement
- A object oscillates with a frequency of 2.44 Hz. At t=0.246 s, the object is located at its amplitude A=+0.15 m.
The position is modeled as x(t)=Acos(ωt+ϕ)
Determine the phase angle (positive value between 0 and 2π):
a. Determine the phase angle (positive value between 0 and 2π):
b. Determine the position of the object at t=0 s.
- Relevant Equations
- w=2pi/T
What I have done so far:
Since x=A, cos(ωt+ϕ) must equal 1
cos-1(1)=0 so -ωt=ϕ
ω=2pi/(1/f)=15.3
ωt=3.7=ϕ
