Question

A small cart with low friction wheels is attached to a sturdy wall with a high quality spring that has negligible internal damping. Use a coordinate system where the cart is at equilibrium when the carts indicator points to 0. The cart at rest is shown in the figure at the right. The cart has a mass of 0.750 kg and the spring constant is 12 N/m. |

2. Velocity of the cart. **(I have tried answers D and C, for velocity, and they are not correct)**

---Select--- A B C D E F G H None

4. Net force on the cart.

---Select--- A B C D E F G H None

5. Force the spring exerts on the cart.

---Select--- A B C D E F G H None
