Question 28
Uniform circular motion: A person on a sled coast down a hill and then goes over a slight rise with a speed of 2.8 m/s. The top of this rise can be modeled as a circle of radius 4.0 m. The sled and occupant have a combined mass of 110 kg. If the coefficient of kinetic friction between the snow and the sled is 0.10, what friction force is exerted on the sled by the snow as the sled goes over the top of the rise?
