A particle with a mass of 3.00 1020 kg is oscillating with simple harmonic motion with a period of 7.00 105 s and a maximum speed of 4.50 103 m/s.
(a) Calculate the angular frequency of the particle.
rad/s
(b) Calculate the maximum displacement of the particle.

ω=2π/T=2•3.14/7•10⁻⁵=…
x(max) =A.
v(max)=Aω =>
A= v(max)/ω=…
