Astunt man is attempting to ride his bike through the loop of a track. the
combined mass of the stunt man and his bike is 101 kg. (a) if the radius of
the loop is 10.1 m and he is traveling at 22.5 m/s, what is the normal force
from the track when he is at the top of the loop?
(b.) what is the minimum speed the stunt man can be traveling and still
make the loop?

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
