Suppose that you and two classmates are discussing the design of a roller coaster. one classmate says that each summit must be lower than the previous one. your other classmate says this is nonsense, for as long as the first one is the highest, it doesn't matter what height the others are. what do you say

The other classmate is right.

Explanation:

As long as the first one is the highest, it does not matter what height are other hills or peak as energy is conserved during its motion.

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."
