An electric motor will pull the coaster to the top of the first
hill.
After the coaster has been pulled to the top, no more external energy
will
be added to it.
How high is
your first hill?
Choose one of the selections on the left
and then click on the
button below.
Hint:The
amount of energy the coaster has to complete its journey around
the
track
depends on the potential energy it has due to its height at the
beginning. There is a
relationship between the height of this hill and
the speed of the coaster.
