The question below refers to the following graph.

assuming the input of energy continues for another 5 seconds, where will the particle be?

equilibrium
positive maximum
negative maximum
cannot be determined

Equilibrium. The image shows a zero displacement every 5 seconds on the graph. With 5 more seconds it will be at equilibrium again.
