Problem

A block attached to an ideal horizontal spring executes simple harmonic motion. It is observed to have speed

0.60\,\text{m\,s}^{-1}

when its displacement from equilibrium is

0.040\,\text{m}

and speed

0.40\,\text{m\,s}^{-1}

when the displacement is

0.060\,\text{m}

. What is the amplitude of oscillation? (a)

0.080\,\text{m}

(b)

0.072\,\text{m}

(c)

0.060\,\text{m}

(d)

0.100\,\text{m}
