A mass is undergoing simple harmonic motion. When its displacement is 0, it is at its equilibrium position. At that moment, its speed is _______ and its acceleration is _______.

Respuesta :

Answer:

When X = 0

Speed = maximum    V (max) = ω A

Acceleration = zero       a(max) = - ω^2 A

From x = A sin ω t        sin = 0     so displacement = zero

V = ω A cos ω t             cos = 1 and speed = maximum

a = - A ω^2 sin ω t            sin = 0 and acceleration = zero
