A section of a roller coaster track assumed to be frictionless is shown with two roller coaster cars. The first car has a mass of 60.0 kg and starts from rest at a height of 10.0 m above ground level. The second roller coaster car has a mass of 80.0 kg and is at rest at the bottom of the track. The two cars collide and stick together to each other and together they travel up the track and reach a maximum height H.
