1) In simple harmonic motion, when is the speed at the maximum? Choose all that apply.

???A) when the magnitude of the acceleration is a maximum.

B) ???when the displacement is a maximum

C) when the magnitude of the acceleration is a minimum

D) ????when the potential energy is a minimum.

2) A spring is attached to a hanging mass. The other end of the spring is connected to an electric oscillator which oscillates up and down. The mass is pulled down and released, causing it to oscillate at a frequency of 0.80 Hz. The electric oscillator is then turned on and set to 0.80 Hz. What will happen to the amplitude of the mass? Explain.

3) A wave at a specific time is shown in the graph below. What information about the wave can be deduced from the graph below? Use this information to calculated the period of the wave shown in the figure.
