Q. A car traveling at 17.0m/s runs out of gas while traveling up a 21.0 degree slope. How far up the hill will it coast before starting to roll back down?

Q. A string is wrapped around a disk of mass m = 1.7 kg and radius R = 0.08 m. Starting from rest, you pull the string with a constant force F = 7 N along a nearly frictionless surface. At the instant when the center of the disk has moved a distance x = 0.12 m, a length d = 0.34 m of string has unwound off the disk.
