Prompt:

Use the terms momentum, impulse, mass, velocity, and collision to explain what happened when the dart hit the cart.

Sentence Starters:

Claim: The total momentum of the system changed/stayed the same because...

Evidence: Before the collision, the dart had mass and was moving at __ m/s, so it had momentum.

After the collision, the dart and cart moved together at __ m/s, showing that...

Reasoning: Momentum is conserved, so when the dart stuck to the cart, they...
