2. If a spring has a spring constant of 400 N/m, how much elastic potential energy is stored when the spring is stretched by 0.25 m?

Suppose you plot the distance traveled by an object at various times and you discover that the graph is not a straight line. what does this indicate about the object's acceleration?
