, Calculations for Activity 1. Elastic Collision with Equal Masses
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 = ����+ ����
Momentum after the collision = ����′ + ����′
����+ ����= ����′ +

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).

Momentum on the left-hand side (before the collision)
Total left-hand side momentum =momentum of cart A and B before the collision
