A 0.20 kg object, attached to a spring with spring constant k = 10 N/m, is moving on a horizontal frictionless surface in simple harmonic motion of amplitude of 0.080 m. What is its speed at the instant when its displacement is 0.040 m? (Hint: Use conservation of energy.)

Answer 1

Here's another hint: The total energy is

(1/2)k*(Amplitude)^2

When displacement is half the amplitude, potential energy is 1/4 of the total energy. The rest is kinetic.
