The range would be 1.47 m if the marble did not rotate and
did not lose any mechanical energy. The range would be 1.24
m if the marble rolls without slipping but does not lose any
mechanical energy.
A relative error of -24% from 1.47 m is 1.12 m, which has a
relative error of -10% from 1.24 m. A range of 0.97 m has a
relative error of -22% from 1.24 m.

setup
the following: top of the plastic tube was 60cm from the top of thefrom the edge
lab table, 90.07cm from the lab table to the floor, and the marble's
range was 97cm. I figured that it should've landed 147cm
of the lab table (about 34% error). I've tried differenttube heights
and my error would fluctuate (the best being 24% error).
I'm curious if others had done something similar and suggestions for
improving my setup.
