Your van is parked on a steep hill with a 12o slope with the van held in place by the parking brake.
A) Find the magnitude of the frictional force that hold your van in place.
B) The coefficient of static friction between your van's tires and the road when wet is 0.25. Find the largest angle slope on which you can park your van in the rain therefore that it will not slide down the hill?
C) The coefficient of kinetic friction between your van's tires and the wet road surface is 0.20. If someone gave your van a push on the wet hill with the slope and it started to slide down the hill, find what would its acceleration be?
