A skateboarder is attempting to make a circular arc of radius r = 11 m in a parking lot. The total mass of the skateboard and skateboarder is m = 86 kg. The coefficient of static friction between the surface of the parking lot and the wheels of the skateboard is μs = 0.59 . He speeds up very slightly and begins to slide. The coefficient of kinetic friction is μk = 0.21. What is the new magnitude of his radial acceleration in m/s2?
