```Two frictionless roller-coaster cars sit atop identical roller
coaster tracks.  The two roller-coasters meet at the bottom to form
a single continuous roller-coaster track.  The more massive car
has mass M, the less massive has mass m.  Neglect air resistance.
a) If the two cars are released simultaneously from rest, describe
in words where the two cars collide.
b) If when they collide, the two cars stick together, calculate
the highest height the two cars will ultimately reach after they
stick together, expressed in relation to their original height.
```

The highest height (h) the two... View the full answer

a) at bottom both the cars will collide b) Height... View the full answer
