Problem

0.50\,\text{kg}

cart is attached to a horizontal spring with spring constant

200\,\text{N}\!\cdot\!\text{m}^{-1}

and oscillates with amplitude

0.10\,\text{m}

. What is the speed of the cart when it is

0.060\,\text{m}

from equilibrium? a)

2.3\,\text{m}\!\cdot\!\text{s}^{-1}

1.6\,\text{m}\!\cdot\!\text{s}^{-1}

0.80\,\text{m}\!\cdot\!\text{s}^{-1}

1.3\,\text{m}\!\cdot\!\text{s}^{-1}
