To analyze the momentum changes in a collision scenario involving two balls (red and green), we can follow these steps:

### Known Conditions:
1. **Momentum** is defined as the product of mass and velocity: $$ p = mv $$.
2. In a closed system, the total momentum before a collision is equal to the total momentum after the collision, assuming no external forces act on the system.

### a. What happens to the momentum of the red ball after the collision?
- **Before the collision**: The red ball has a certain momentum based on its mass and velocity.
- **After the collision**: The momentum of the red ball will change depending on the nature of the collision (elastic or inelastic). If it collides elastically, it may retain some momentum, but if it collides inelastically, it may lose momentum to the green ball.

### b. What about the green ball?
- **Before the collision**: The green ball also has its own momentum.
- **After the collision**: Similar to the red ball, the green ball's momentum will change. If it was initially stationary, it will gain momentum from the collision. If it was moving, its momentum will change based on the interaction with the red ball.

### c. What about the total momentum of both the red and green ball?
- The total momentum of the system (both balls) before the collision will equal the total momentum after the collision. This is a fundamental principle of conservation of momentum. Therefore, regardless of how the individual momenta of the red and green balls change, the total momentum remains constant.

### Summary:
- The red ball's momentum may decrease or change direction after the collision.
- The green ball's momentum may increase or change direction after the collision.
- The total momentum of both balls remains constant before and after the collision.

If you have specific values or a simulation to refer to, we could analyze the exact changes in momentum quantitatively.
After the collision: - The red ball's momentum changes. - The green ball gains momentum. - The total momentum of both balls stays the same.

Watch the simulation, and then pause it once the vectors have changed.
