Question

Hello, I need some help with this problem.

**Problem 1:**

A block of copper with mass 1.8 kg sits on a low-friction surface. A bullet of mass 0.006 kg traveling horizontally just before the collision bounces off the block as shown in the diagram, looking down from above. We take the plane of the motion to be the xy plane (with z pointing outward, toward the viewer).

**Diagram Explanation:**

- The diagram shows a block with a mass of 1.8 kg represented by a square.
- A bullet with a mass of 0.006 kg is depicted as moving towards the block initially with a velocity of \(\langle 70, 30, 0 \rangle\) m/s in the xy plane.
- After the collision, the bullet moves away with a velocity of \(\langle 40, -20, 0 \rangle\) m/s.
- The x and y axes are shown with an arrow at the origin indicating the direction.

**Question:**

What is the velocity of the block of copper just after the collision? Start from a fundamental principle, and show all your work. *Your answer must be a 3-component vector.*
