Suppose a cart with no fans has a starting velocity of 2 m/s. What will be the velocity of the cart when it reaches a wall?

Beyond the petition Neptune a field of smaller bodies orbits the Sun. Some scientists think these objects are the remains of material that formed the early solar systems. Use what you know about how solar systems form to evaluate this hypothesis.
