The Outlaw Run roller coaster in Branson, Missouri, features a track that is inclined at 84 ∘ below the horizontal and that spans a 49.4-m (162 ft) change in height.
a)If the coefficient of friction for the roller coaster is μk = 0.28, what is the magnitude of the friction force on a 1600-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?

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)
