Which of the following is true for a system consisting of a mass oscillating on the end of an ideal spring?

• The kinetic and potential energies are equal at all times.

• The kinetic and potential energies are both constant.

• The maximum potential energy is achieved when the mass passes through its equilibrium position.

• The maximum kinetic energy and maximum potential energy are equal, but occur at different times.

• The maximum kinetic energy occurs at maximum displacement of the mass from its equilibrium position.

A 0. l -kilogram block is attached to an initially unstretched spring of force constant k = 40 newtons per meter as shown above. The block is released from rest at time t = 0.

At what time after release will the block first return to its initial position?
