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.
