The roller coaster in the picture will not make it over the second hill. Pick the answer that best describes why getting over the second hill would be impossible.

• The potential energy gained when climbing the first hill is greater than the kinetic energy required to climb the second hill.
• The potential energy gained when climbing the first hill is equal to the kinetic energy required to climb the second hill.
• Energy is destroyed as the roller coaster car travels on the track.
• The potential energy gained when climbing the first hill is less than the kinetic energy required to climb the second hill.
