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.

The Answer of 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.
