the basic measurements of length, volume, and mass are 1 meter, 1 meter³ and 1kilogram.
One 10-millionth of the distance from the North Pole to the equator would equal one meter.
A cube with sides of one meter has a volume of one meter³.
The mass of 1,000 cubic centimeters of water is very close to (and was originally intended to be exactly) one kilograms.
but today a more precise way to define is available in which:
1 meter is defined as the distance traveled by light in 1/3×10⁸ sec.
The weight of a specific platinum-iridium prototype held by the International Bureau of Weights and Measures is defined as 1 kg.
moreover these measurements are man made and are not absolute and therefore many new units of measurement can be defined as long as they are fundamentally same everywhere.

Between the top of the first and the top of the second loop, the coaster has lost potential energy = mgh, where h = 22.2 - 15 = 7.2m
This energy would have converted to Kinetic. Write out an equation and the masses will cancel out. Does that hint help you to find the solution? If not, I will give you another hint.
