A large spring is used to stop the cars after they come down the last hill of a roller coaster. The cars start at rest at the top of the hill and are caught by a mechanism at the instant their velocities at the bottom are zero. Compare the compression of the spring, x_A, for a fully loaded car with that, x_B, for a lightly loaded car when m_A = 2m_B. A) x_A = x_B. B) x_A = x_B. C) x_A = x_B. D) x_A = 2 x_B. E) x_A = 4 x_B.
