Problem
An object executes simple harmonic motion along the x-axis. As it passes through the equilibrium position moving toward +x, which combination correctly states the signs of its displacement x, velocity v, and acceleration a at that instant?
(a) x=0,v=+,a=+
(b) x=0,v=+,a=−
(c) x=0,v=+,a=0
(d) x=+,v=0,a=−
