A team of 10 Qimmiq is pulling a komatik and its load having a total mass of 1000kg at a constant velocity of 8.1km/h over the frozen tundra. Calculate the coefficient of kinetic friction between the komatikand the snow if the dogs must exert a total force of 922N to keep the komatik travelling at a constant velocity?

It is a cold, icy miserable day in Whitehorse. You find yourself driving along the highway on your way out of town. You are driving a little fast (80km/h) as you approach a very icy corner on the highway, the corner essentially is frictionless. Luckily the engineers realised tourists like you would drive too fast into this corner and designed the corner to be banked and allow cars to safely navigate the 80m radius turn. At what angle did the engineers bank the corner?
