A skateboarder is attempting to make a circular arc of radius r=15 m in a parking lot. The total mass of the skateboard and skateboarder is m= 99kg. The coefficient of static friction between the surface of the parking lot and the wheels of the skateboard is us=0.58. (A) what is the maximum speed, in meters per second, he can travel through the arc without slipping? (b) he speeds up very slightly and begins to slide. The coefficient of kinetic friction is I’m=0.18. What is the new magnitude of his radial acceleration in m/s^2?
