1. Determine the angle of the inclined ramp by measuring the sides of the triangle
formed by the incline and the horizontal.

2. Computing an estimate of the value of the acceleration due
to gravity near Earths surface
The acceleration down and parallel to the track is due to the acceleration of gravity.
We can replace g with the sum of two components that add up to the same value
and direction, namely g,. plus a component perpendicular to the track.
