Question

When are the displacement and acceleration equal to zero for the motion of a mass on a spring?

Answer 1

Just think about the equation: F = -kx

Answer 2

x = A sin (w t)

a = - w^2 sin (w t)

x goes from -A through 0 to +A

when are x and a both = 0?

Answer 3

at the equilibrium position?
