A student is attempting to move a 31-kg mini-fridge into her dorm room. During a moment of inattention, the mini-fridge slides down a 35 degree incline at constant speed when she applies a force of 25 N acting up and parallel to the incline. What is the coefficient of kinetic friction between the fridge and the surface of the incline?

μk=μk=


A car rounds an unbanked curve of radius 95 m. If the coefficient of static friction between the road and car is 0.55, what is the maximum speed at which the car traverses the curve without slipping?



v= m/s
