Understanding Momentum Conservation in Collisions

Before Collision:

Red Cart: 45 kg°cm/s

Blue Cart: 0 kg°cm/s

System: 45 kg°cm/s

After Collision:

Red Cart: 45 kg°cm/s (combined with blue cart)

Blue Cart: Not applicable as it combines with red cart

System: 45 kg°cm/s (combined momentum)

Momentum Change:

Final Answer: The change in momentum for the system, red cart, and blue cart is zero.
