The Outlaw Run roller coaster in Branson, Missouri, features a track that is inclined at 83 degrees below the horizontal and that spans a 49.4-m (162 ft) change in height.
Part A
If the coefficient of friction for the roller coaster is 0.25, what is the magnitude of the friction force on a 1700-kg coaster train?
Part B
How much work is done by friction during the time the coaster train travels along the incline?
Part C
What is the speed of the coaster train at the bottom of the incline, assuming it started from rest at the top?
