Homework Statement
A body oscillates with simple harmonic motion along the x-axis. Its displacement varies with time according to the equation
A=Ai * sin(wt+ (pi/3)) ,
Where w = pi radians per second, t is in seconds, and Ai = 2.4m.
What is the phase of motion at t = 9.4 seconds? Answer in units of radians.
Homework Equations
A is the amplitude.
Ai is the initial amplitude.
w is actually "omega" but I didn't know how to enter that. That is the given angular velocity in rad/s.
Pi is 3.14...
The Attempt at a Solution
I honesty don't know where to start. I just plugged into the equation with the given data and got
-1.78355 meters.
The answer wants radians. Also, it asks for the "phase of motion". The answer I got is just the final amplitude at the given time.
Any help would be appreciated.
Thanks.
