Please help
The Earth's orbit around the Sun is so close to a perfect circle that, when viewed edge on-meaning you're watching something move in a circular path from the outside with your vision aligned with the plane of the circle-its motion appears to be simple harmonic. In effect, you see the Earth moving back and forth past its "equilibrium" point of passing (in front of or behind) the Sun. The Earth's orbital radius is about 1.5 Times 1011 m, its orbital period you know (assume 365.25 days in a year). Write an expression for the Earth's orbit as a function x(t), representing its time-dependent displacement from the equilibrium position of being aligned with the sun (as viewed edge on from, say, the orbit of Jupiter).Explanation / Answer
x(t)= 1.5*10^11*sin 2*pi*t/T=1.5*10^11*sin(1.99*10^-7 t) tis in seconds
