Conservation of Momentum

1. In this case you are to determine, by any means necessary, the mass of the first cart. You may need to do several trials to determine this. The slider bars control the total momentum of the first cart and the mass of the second cart. Remember:

M1V1 = M2V2 Hit the button that says "push" to cause the carts to collide.

Record your experimental values and email them to

2. Determine the combined mass of the carts.

3. Set the Momentum to 1800 and the mass of the cart to 150. Determine how many shots it will take for the cart to reach a velocity greater than 250 m/s. What will the mass of the cart be at that point. Remember, the bullets each thave a mass of 1 and stick to the cart.

Do the same experiment for a cart mass of 50.
