Question 2

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.

xA = xB.

◦
xA = xB.

◦
xA = xB.

◦
xA = 2 xB.

◦
xA = 4 xB.
