Final answer:
The average acceleration of cart B during the 0.20-second interaction is 25 m/s². The correct option s C)
25 m/s2.
Step-by-step explanation:
The average acceleration of cart B can be calculated using the formula a = F/m, where a is the acceleration, F is the force, and m is the mass of the object. In this case, the force exerted by the spring is 50 N and the mass of cart B is the same as cart A. Therefore, the average acceleration of cart B is 50 N divided by the mass of cart B.
Since the masses of both carts are equal, the average acceleration of cart B is also equal to the average acceleration of cart A. The answer is 25 m/s² (C).
