Homework Statement
A particle is subjected to two simple harmonic motions given by
x1=2[sin(100πt)]
x2=2[sin(120πt+{π/3})] where x is in centimetre and time is in seconds.
Find the displacement of the particle at t=1/80
Homework Equations
The Attempt at a Solution
The answer given in my book is found by simply putting the value of time in both equations and adding the displacements..
But I am confused. How can we add the displacements even though the angular frequencies of both SHM's are different?
