Eloforo Collision After Collision Cart A of mass m}; travels tou-'ard cart 13 of mass ring: which is initially at rest. The two carts stick together after the collision. The position as of the center of mass of cart A is recorded at equal time internals before and aer the collision: as shown above. Based on the data, what can he concluded about the relatit'e masses of carts A and E? {A} mA 3: my; (B) in}; s: mg (C) mA = mg (D) The answer cannot be determined without knowing the initial speed of cart A
