Question

What is the value of the phase angle if the initial velocity is positive and the initial displacement is negative?

Answer 1

Answer:

The angle φ is known as the phase shift of the function. The velocity of the mass on a spring, oscillating in SHM, can be found by taking the derivative of the position equation: v(t)=dxdt=ddt(Acos(ωt+φ))=−Aωsin(ωt+ϕ)=−vmaxsin.
