Can you help with this? Thank you very much.

Here is my data chart.

Activity 3: Elastic Collision: Mass Added to Cart B Data Table 3 Table 3A. Cart A before collision.

Elastic Collision: Mass Added to Cart B. Apply the law of conservation of momentum to the two-cart system by calculating the momentum before and after the collision. Helpful equations: Momentum before the collision = mAVA + mEVE Momentum after the collision = mAVA' + mEVE MAVA + MBVB = mAVA + MBVB first value - second value Percent difference = first value + second value x 100% 1. Calculate the momentum of the system before the collision (the left side of the equation) and after the collision (the right side of the equation). 2. Calculate the percent difference between the two values. 3. Explain any difference in the values before and after the collision.Questions for Momentum: 1. The law of conservation of momentum states that the total momentum before a collision equals the total momentum after a collision provided there are no outside forces acting on the objects in the system. What outside forces are acting on the present system that could affect the results of the experiments? 2. What did you observe when Cart A containing added mass collided with Cart B containing no mass? How does the law of conservation of momentum explain this collision? 3. In one of the experiments, Cart A may reverse direction after the collision. How is this accounted for in your calculations
