Question
The Outlaw Run roller coaster in Branson, Missouri, features a
track that is inclined at 81° below the horizontal and that spans a
49.4-m 1162 ft2 change in height. (a) If the coefficient of friction
for the roller coaster is mk = 0.29, what is the magnitude of the
friction force on a 1700-kg coaster train? (b) How much work is
done by friction during the time the coaster train travels along the
incline? (c) What is the speed of the coaster train at the bottom of
the incline, assuming it started from rest at the top?
