Two objects can move in either direction along the $x-$axis. The two objects collide. As a result of the collision, object $1\text{'}$s velocity vector changes, $v_x=-10\frac{m}{s}.$

Consider the following statements about this situation. Select all statement$($s$)$ that must be true.

Choose all that apply.

Object $1$ is moving faster after the collision than it was before the collision.

Object $1$ is moving slower after the collision than it was before the collision.

Whether object $1$ is moving faster or slower after the collision than it was before the collision cannot be determined using only the information given.

Object $1$ moved in the positive direction before the collision, and in the negative direction after the collision.

Object $1$ moved in the negative direction before the collision and in the positive direction after the collision.

Object $1$ moved in the negative direction both before and after the collision.
