A Large Spring Is Used to Stop the Cars After $\frac{1}{2}$

question 31

Multiple Choice

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, xA, for a fully loaded car with that, xB, for a lightly loaded car when mA = 2mB.

• A)xA = \(\frac{1}{2}\) xB.
• B)xA = xB.
• C)xA = \(\sqrt{2}\) xB.
• D)xA = 2 xB.
• E)xA = 4 xB.
